Ethnopharmacological Relevance. Development of resistance to antimalarial drugs by Plasmodium falciparum is still rampant, and there is an urgent need for novel drugs to either standalone or to partner artemisinin for treatment of malaria. Traditionally, plants have, over the years, been a good source of antimalarial drugs. Efficacy and safety of such plants need to be scientifically authenticated. Aims, Materials, and Method. This study investigated the in vitro antiplasmodial activity, cytotoxicity, and genotoxicity of aqueous extracts of Acanthospermum hispidum DC, Alstonia boone (De Wild), Cocos nucifera L, Cymbopogon citratus (DC.) Stapf, Morinda lucida Benth, Psidium guajava, Phyllanthus niruri L, and Senna siamea Lam. Results. Five out of the eight plants, A. boonei stem bark, S; siamea Lam root, M. lucida Benth leaves, P. niruri, and A. hispidum DC whole plants, showed varying degrees of antiplasmodial activity against the asexual stage of the parasite. The most active extract against chloroquine-sensitive (3D7) and chloroquine-resistant (Dd2) P. falciparum strains is the A. hispidum extract which yielded a mean inhibitory concentration at 50% (IC50) of 3.66 µg/ml and 3.71 µg/ml for 3D7 and Dd2, respectively. This was followed by S. siamea Lam with 3.95 µg/ml for 3D7 and 4.47 µg/ml for Dd2. The IC50 values of the A. boonei extract against 3D7 and Dd2 P. falciparum parasites were 5.13 µg/ml and 3.62 µg/ml, respectively. For the M. lucida Benth extract, the least IC50 value was 6.46 µg/ml. All five extracts exhibited dose-dependent antiplasmodial activity. Assessment of the genotoxic effects the A. hispidum extract by the comet assay revealed substantial damage to P. falciparum DNA. Conclusion. This study demonstrates that the crude extract of A. hispidum DC, one of the plants used traditionally to treat malaria, inhibits the growth of P. falciparum in vitro and could be a potential source of antimalarial drug. The report has highlighted genotoxic and cytotoxic effects of the selected plant extracts on human leukocytes as well.

ABSTRACT Cases of sporotrichosis in humans and animals without satisfactory clinical response have increased, a warning sign of strains resistant to conventional antifungal agents. The urgent search for alternative therapies was an incentive for research on medicinal plants with anti-Sporothrix spp. properties. A bibliographic survey was performed based on scientific papers about in vitro and in vivo antifungal activity of essential oils and extracts of plants in differents solvents against the fungal of the Sporothrix schenckii complex. The study methodology consisted of a literature review in Google Scholar, Science Direct, Pubmed, Bireme and Springer link with papers from 1986 to 2015. We found 141 species of plants that were investigated, of which 100 species were concentrated in 39 botanical families that had confirmed anti-Sporothrix activity. Combretaceae, Asteraceae and Lamiaceae represented the botanical families with the greatest number of plants species with antifungal potential, using different methodologies. However, there are few studies with medicinal plants in experimental infection in animals that prove their activity in the treatment of sporotrichosis. It reinforces the need for further research related to standardization of in vitro methodologies and in vivo studies related to safety and to toxicity potential of these plants with anti-Sporothrix spp. activity.

Medicinal plants have been historically used as treatment for different kinds of human diseases. In this study, hot water (HW) extract of five Taiwanese traditionally used medicinal plants was evaluated for their in vitro anti-leukemic (including anti-K562, L1210, P3HR1, Raji and U937 leukemia cells) and antiviral (including HSV-1 and HSV-2) activities. Results showed that Blumea lacera exhibited broad anti-leukemic activity at magnitudes ranging from moderate to mild and Ixeris chinensis is effective at inhibiting the proliferation of K562 cells. B. lacera and Tithonia diversifolia suppressed the replication of HSV-1 and HSV-2, and had IC 50 values below 100 μg/ml. The medicinal plants showed no cytotoxic effect at concentrations that inhibited HSV infection. It was, therefore, concluded that the HW extract of tested medicinal plants exhibited anti-leukemic and antiviral activities at different magnitudes of potency.

Abstract The present study investigates the potential role of medicinal plants Citrullus colocynthis and Tephrosia apollinea in ameliorating the oxidative stress developed during the generation of reactive oxygen species. Organic extracts of different organs (leaf, stem and root) of these medicinal plants obtained in n-hexane, chloroform, n-butanol and water were assayed for radical scavenging, total antioxidant capacity, anti-lipid peroxidation and reduced glutathione. The total phenolic content (TPC) of both selected medicinal plants was also evaluated. The results indicated that extracts of T. apollinea leaf, stem and root have higher TPC compared to those of C. colocynthis. Similarly, the results of the present study revealed higher bioactivity of C. colocynthis than that of T. apollinea in various antioxidant assays. Various plant parts of each plant were also compared.

The problem of biodiversity conservation and rational use of natural resources remains one of the most pressing problems for countries around the world. To maintain the stability of biological resources a sufficiently developed basis for their reproduction is required, which, in turn requires a preliminary study of the developmental features of individual organisms both in the natural environment and during their introduction into the cultural environment. A special place among the spice plants is occupied by the Lamiaceae Lindl. family. It is rich in medicinal and essential oil plants, which are widely used in family medicine, as well as in folk medicine and food industry, perfumery and cosmetic industries. Such plants include Origanum vulgare and Salvia officinalis. In addition, both plant species are added as phytobiotics to animal feed. The article deals with sterilization of seeds of medicinal plants Origanum vulgare L. and Salvia officinalis L. and the effect of sterilization methods on seed germination. For in vitro cultivation an aseptic, undamaged pure culture was obtained from the original plant material, and the most optimal method for sterilizing the seeds of these medicinal plants was chosen.

The prevalence of obesity is increasing globally. Despite the availability of a variety of anti-obesogenic drugs, including therapies under clinical development, these treatments are often indicated for patients with severe obesity, making them unsuitable for patients with mild obesity or for preventative use. In Thailand, traditional remedies employing medicinal plants are widely used to maintain health and treat disease. These treatments are generally inexpensive and readily available at markets, making them good treatment options for preventing obesity. To evaluate the anti-obesogenic potential of Thai medicinal plants, we employed three in vitro methods: pancreatic lipase inhibition, lipolysis enhancement, and lipid accumulation reduction assays. Among 70 Thai medicinal plants, Eurycoma longifolia Jack, Tiliacora triandra Diels, and Acacia concinna (Willd.) DC. were selected as the most favorable candidates because they exhibited anti-obesogenic activity in all three assays. These medicinal plants are expected to have efficient anti-obesogenic effects, making them promising candidates for further study.

Herbal plants produce a diverse range of bioactive molecules, making them a rich source of different types of medicines. Thus, proper scientific evidence or assessment has become the criteria for the acceptance of herbal health claims. Plants-based antioxidants are now preferred to synthetic ones because of safety concerns. There is an increasing interest in natural antioxidants e.g. Polyphenols, present in medicinal and dietary plants, which might help prevent oxidative damage. Natural antioxidant increases the antioxidant capacity of plasma and reduces the risk of disease. As such developing a polyhedral formulation will definitely produce a synergistic effect as needed comparable to standard drugs that are available in the market all over the world. The polyherbal formulation, which has a combination of medicinal herbs such as Zingiber officinale (sukku), Nigella sativa (karunjeeragam), Plectranthus amboinicus (karpooravalli), Pipeer cubeba (Vaal melagu), Trigonella foenum graecum (venthayam) powder was tested for its an antioxidant activity phenolic and alkaloid contents in vitro. The purpose of the present study was to investigate the In-vitro antioxidant phenolic and alkaloid content of polyherbal formulation and its application for treating life-threatening diseases such as cancer, cardiac disease, and diabetes mellitus. In this paper, we report the result of such studies in order to orient future investigations towards the finding of new, potent safe, and easily available food antioxidants.

The aim of this article was to review some of the new and commonly used medicinal plants in the treatment of kidney stones, emphasizing medicinal uses, pharmacological activity, and research study of medicinal plants. Renal stones are a common problem worldwide with substantial morbidities and economic costs. The high economic burden associated with kidney stones is linked mainly with healthcare costs. In vitro and in vivo studies on alternative treatment of kidney stones have been searched by using words such as phytotherapy of kidney stones, medicinal plants used in kidney stones, and lithotriptic activity of plants. Articles reviewed showed that medicinal plants have lithotriptic potential. Medicinal plants may be useful in treatment of kidney stones. This study was aimed to explore and elaborate the efficacy and availability of alternative treatment for kidney stones and to provide safe, cost effective, and efficacious management options as well as reduce the burden of disease. Cost effectiveness may enable improvements in treatment efficiency that can benefit patients and the healthcare system. Further randomized clinical trials should be conducted to evaluate the safety and efficacy of medicinal plants.

The study was designed to evaluate the preliminary biological activities of crude methanol extracts of the leaf of Justicia gendarussa, Sansevieria trifasciata and Hydnocarpus kurzii and their organic soluble partitionates. The polyphenol content was determined spectrophotometrically and expressed as gallic acid equivalents. The total phenolic content was found to vary for different test samples ranging from 1.45 ± 0.25 mg to 40.73 ± 0.22 mg of GAE/ gm of dried extract. The antioxidant potential was evaluated by DPPH free radical scavenging assay using butylated hydroxytolune (BHT) and ascorbic acid as standards. In the assay, the CSF of H. kurzii and the PESF of J. gendarussa revealed the highest free radical scavenging activity with IC50 values 3.25 ± 0.05 ?g/ml and 24.68 ± 0.26 ?g/ml, respectively. The brine shrimp lethality bioassay was utilized to evaluate the cytotoxicity. The chloroform soluble fraction (CSF) and methanol extract (ME) of J. gendarussa exhibited strong cytotoxicity with LC50 values of 0.002 ?g/ml and 0.06 ?g/ml, respectively. The membrane stabilizing activity was assessed by evaluating hemolysis of RBC in hypotonic solution and was compared with acetyl salicylic acid. On the other hand, the chloroform soluble fraction of J. gendarussa and aqueous soluble materials of S. trifasciata produced 75.60% and 75.0% inhibition of hemolysis of RBC, respectively as compared to 77.9% inhibited by acetyl salicylic acid (0.10 mg/ml).

Background: This study sought to investigate the antimicrobial activity of six plants used in traditional medicine in Africa. Methods: The antimicrobial activity of the six medicinal plant extracts (aqueous and ethanol) were evaluated against Proteus mirabilis (ATCC 21784), Pseudomonas aeruginosa (ATCC27856) were Aspergillus fumigatus using the agar-well diffusion protocol. The activities of these extracts were compared with the positive controls chloramphenicol and griseofulvin. Similarly, the phytochemicals from the extracts were qualitatively assayed and their percentage yield calculated by standard methods. Results: The bacterial organisms used, P. mirabilis and P. aeruginosa, were slightly-to-highly susceptible to aqueous and ethanolic extracts from the various test plants, while A. fumigatus was insensitive to the treatments. The ethanolic extracts of the sampled plants showed superior inhibitory performance on the target bacteria to the aqueous extracts. Aqueous and ethanolic extracts of Aframomum melegueta, Moringa oleifera and Cola nitida showed inhibitory consistency against the target bacteria. Superior inhibitory activity was observed for ethanol extracts of A. melegueta seed and M. oleifera pod against P. mirabilis and P. aeruginosa. Variations in phytochemicals were noticed across solvents and plant parts for all plants. Phenols were detected in the aqueous and ethanolic extracts of C. nitida and Cola acuminate, but relatively appeared denser in extracts of A. melegueta seed and Chrysophyllum albidium fruits. The extracts of C. nitida, C. acuminate and A. melegueta tested positive for the presence of flavonoids, which were undetected in C. albidium and M. oleifera seed and pod extracts. None of the extracts showed the presence of every phytochemical assayed during the study. Conclusions: Extracts of the medicinal plants assessed in this study showed antibacterial potential. Developing new methodologies that preserve the bioactive potency of phyto-extracts for optimal microbicidal activity is promising for development of safe, non-reactive pharmaceuticals.

Background: Plants in traditional healthcare services in West Africa were selected based on ethnobotanical data for this study. Aqueous and ethanol extracts from these plants’ parts were comparatively screened for phytochemicals and in vitro antimicrobial activity. Methods: The antimicrobial activity of five medicinal plants’ extracts (aqueous and ethanol) were evaluated against Proteus mirabilis (LHC201), Pseudomonas aeruginosa (LHC181) and Aspergillus fumigates (LUML56) using the agar-well diffusion protocol. Retailed chloramphenicol and griseofulvin were used as positive controls respectively. Phytochemicals and percentage yield were determined by modified standard methods. Results: The target bacteria showed varied degrees of susceptibility to both aqueous and ethanol extracts. A. fumigates was insensitive to the treatments. The ethanol extracts of the sampled plants’ parts showed better inhibitory performance against the target bacteria compared to aqueous extracts. Aqueous and ethanol extracts of Aframomum melegueta, Moringa oleifera and Cola nitida showed marginal difference in inhibitory activity with higher inhibition zones observed for the ethanol extracts of A. melegueta seed and M. oleifera pod against the target bacteria. Phytochemicals composition and density observed in extractants and plants’ parts also varied. Phenols were detected in both the aqueous and ethanolic extracts of C. nitida and C. acuminata, but appeared relatively richer in extracts of A. melegueta seeds and C. albidium fruits. C. nitida, C. acuminate and A. melegueta extracts were positive for flavonoids which were undetected in C. albidium fruits, M. oleifera seeds and pod extracts. No single extract had all the phytochemicals assayed. Conclusions: Screened extracts of medicinal plants’ parts used for this study showed promise antibacterial and resource for developing safer pharmaceutics. Optimization of the antibacterial potential of the extracts for commercial exploitation requires further studies. This study has provided information on the antibacterial property of C. albidum fruits which was hitherto underutilized for traditional medicine purpose.

The present study was aimed to examine and compare the antibacterial activity of hot methanolic extract of medicinal plants viz. Portulaca oleracea (purslane), Syzygium cumini (L.) (jamun), Psidium guajava (L.) (guava). Antibacterial activity was carried by using agar well diffusion method, against Gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) and Gram-negative bacteria (Escherichia coli). Results indicated that all the three plant extracts possess antibacterial property against Gram-positive bacteria and no activity was found against Gram-negative bacteria. Moderate zone of inhibition against Staphylococcus aureus and Bacillus subtilis was exhibited by S. cumini (L.) (11mm and 12mm) and P. guajava (L.) (10mm and 11mm) and weak zone of inhibition was exhibited by P. oleracea (5 mm and 6mm). In conclusion, S. cumini (L.) and P. guajava (L.) possess bettercapabilities of being a good candidate in search for natural antibacterial agent against infections and diseases causing Gram-positive bacteria as compared to P. oleracea.

No single extract had all the phytochemicals assayed. Conclusions: Screened extracts of medicinal plants’ parts used for this study showed promise antibacterial and resource for developing safer pharmaceutics. Optimization of the antibacterial potential of the extracts for commercial exploitation requires further studies. This study has provided information on the antibacterial property of C. albidum fruits which was hitherto underutilized for traditional medicine purpose.

In a continuing effort to discover more anti-inflammatory medicinal plants in China, the anti-inflammatory activities of 101 extracts from different parts of 84 traditional medicinal plants were evaluated by a panel of in vitro and in vivo assays. Nuclear factor-kappa B (NF-κB) inhibitory effects were determined by luciferase assay in stably transfected Hela cells. Cytotoxic activities were assessed using the MTT assay. Inhibitory effects on LPS-induced nitric oxide production and proinflammatory mediators were assessed by Griess reaction and Real-Time PCR analysis, respectively. In vivo anti-inflammatory activities were examined by xylene-induced mice ear edema model. In total, 22 extracts showed promising NF-κB inhibitory effects whereas 9 of them did not affect the cell viability. The 9 hit extracts were active in at least one of the subsequently performed in vitro pharmacological test systems. The extract from Hemerocallis minor (root) was selected to perform the in vivo study because it demonstrated significant suppressive effects in all the in vitro assays. Results showed that the extract of Hemerocallis minor (Root) was able to alleviate ear edema effectively in xylene-induced mice ear edema mode. Collectively, our study provides evidence for the potential anti-inflammatory effects of the medicinal plants traditionally used in China. Further phytochemical and pharmacological studies remain to be clarified.

Methane gas produced by ruminants during feed fermentation contributed to global warming as well as poor efficiency of food utilization. Mitigating ruminal methane production through anti-microbial feed additive has serious health implications. A preliminary study of the potential of medicinal plants and spices from Edo and Rivers State, as possible replacement to antibiotic feed additives was carried out. Medicinal plants and spices were purposefully sampled, dried at 40oC, milled and 10 mg was added with 190 mg of substrate in a preweighed nylon incubation bags. Bags and their contents were incubated using 30 mL of buffered rumen liquor in 100 mL syringes following the standard procedure of in vitro fermentation. Variables monitored were 24h total gas volume, short chain fatty acids (SCFA) methane (CH4 ) gas, dry matter degradability (DMD) as well as some chemical, cell wall and anti-nutritive components. Results revealed that adding the medicinal plants and spices as feed additives did not depress gas production in most cases (19.5 – 29.50 mL, 17.75 – 30.00 mL and 12.00 – 29.00 mL for Edo medicinal plants, Edo spices and Rivers medicinal plants respectively) and also did not depress DMD (> 50%). Azadirachta indica stem reduced CH4 production mostly by 53.56% while Dennttia tripetala did by 47.69% among the Edo medicinal plants and spices, respectively. In Rivers State, Amaranthus spinosus gave the highest value of 60.33% CH4 reduction. In the same bracket of similar and good CH4 reduction potentials were Alstonia boonei leaves (49.06%), Newbouldia laevis root (41.50%), Euphorbia heterophyla (37.97%), Allium crispum (47.31%), Allium cepa (46.80%), Aframomum mueguata (46.54%), Capsicum annum (47.32%), Ageratum conyzoides (56.52%), Lagenaria breviflora (48.03%) and Centrosema molle (45.08%). All the medicinal plant and spices with potential for CH4 reduction had corresponding high SCFA values (0.46 – 0.65 Mmol) with tannin (%) and saponin (%) contents of 0.011 – 17.50 and 0.01 – 2.40 respectively. Conclusively, the medicinal plants and spices demonstrated good potentials for reducing rumen methane production in vitro and may be subjected to further in vivo studies.

Development of theoretical bases of optimization of the production process of biologically active substances in the cultivation of medicinal plants by modern methods of biotechnology is one of the main tasks of fundamental research in this area.
The aim of this study was to study the content and features of the accumulation of elements in regenerants of medicinal plants grown on the nutrient medium Murashige-Skoog with different content of phytohormones.
Regenerant plants in vitro culture actively accumulate elements (K, P, Ca, Mg, Na, Zn, Mn, Fe, B, Al, Cu, Pb, Sr, V, Cr, Ag, Mo, Ti, Ni, Co , Se, Cd). The content of the trace elements Mn, Zn and Cu that we studied was at the level of normal values for the vegetation of the continents, Fe in P. alba regenerants – much higher. The content of heavy and toxic metals Pb, Cd, As, Cr, Ni did not exceed the normal level in plants and the acceptable level for dietary supplements, plant-based tea, and medicinal plant materials.
The high dependence of the accumulation of elements in plants-regenerants Iris spuria Art And Soul variety on the content of hormones in the nutrient medium was noted. Representatives of all three groups (macronutrients, trace elements and ultramicroelements) had a similar curve diagram. The maximum peak was located at a concentration of 2.5 µm BAP with auxins, then the coefficient decreased by 5 µm BAP, and the next lower peak was observed at 5.0 µm BAP+A. the Lowest value of KN was at a concentration of 7.5 µm BAP. The introduction of auxins at this BAP concentration stimulated another peak, and then the accumulation coefficient tended to increase at a concentration of 10.0 µm BAP. The revealed dependence makes possible the regulation and directed accumulation of elements necessary for the researcher in plant tissues.

The emergence and spread of antibiotic resistance, as well as the evolution of new strains of disease causing agents, are of great concern to the global health community. Effective treatment of a disease entails the development of new pharmaceuticals or some potential source of novel drugs. Commonly used medicinal plants of our community could be an excellent source of drugs to fight off this problem. This study is focused on exploring the antimicrobial properties of the plants that are commonly being used as traditional medicines. The antimicrobial potential of four different plant extracts was screened against twelve pathogenic microorganisms and two reference bacterial strains. Methanolic extracts of Oxalis corniculata, Artemisia vulgaris, Cinnamomum tamala, and Ageratina adenophora were subjected to a test of their antimicrobial properties by agar well diffusion method. The result indicated that most of the extracts exhibited antimicrobial properties. The highest potential was observed in the extract of O. corniculata against Escherichia coli, Salmonella Typhi, MDR Salmonella Typhi, Klebsiella pneumoniae, and Citrobacter koseri with zone of inhibition (ZOI) of 17 mm, 13 mm, 16 mm, 11 mm, and 12 mm, respectively. Oxalis corniculata also showed the highest MIC against test organisms. The methanolic extract of Artemisia vulgaris, Cinnamomum tamala, and Ageratina adenophora showed efficacy against Staphylococcus aureus. Ageratina adenophora also showed antifungal activity against Rhizopus spp. The experiment confirmed the efficacy of some selected plant extracts as natural antimicrobials and suggested the possibility of employing them in drugs for the treatment of infectious diseases caused by the test organisms.

AbstractCystic Echinococossis is a serious zoonotic parasitic infection caused by Echinococcus granulosus species complex. The current study was designed to evaluate the in-vitro antiprotoscolices effect of alcoholic extracts of three selected medicinal plants including Buxus Wallichiana, Berberis vulgaris and Euphorbia heliscopia against Echinococcus granulosus. Fertile hydatid cysts were collected from livestock and viability of the protoscolices was confirmed by 0.1% eosin red stain method. Protoscolices were subjected to three different concentrations of alcoholic extracts (10mg/ml, 30mg/ ml and 50mg/ml) for 10, 20 and 30 min. The highest efficacy was shown by B. vulgaris (97.92%) followed by B. wallichiana (65.98%) and E. heliscopia (61.22%) respectively, after exposure of 30 minutes at 50mg/ml concentration, that lead to the significant reduction in the viability of protoscolices. Alkaloids, flavonoids, tannins and saponnins were identified qualitatively and weighted quantitatively, that might help in the identification of bioactive compounds involved in selective action on the tegument layer of protoscolices. Alcoholic extracts of all the three selected medicinal plants showed toxic activities against protoscolices of Echinococcus granulosus. These findings suggest that all the selected medicinal plants could be a promising source of potent antiprotoscolices effect. However, the mechanism by which plant extracts killed protoscolices and also their safety for living cells are unclear and need to be investigated further.

Modulation of nitric oxide (NO) may offer novel approaches in the treatment of a variety of diseases, such as Alzheimer’s, cardiovascular disease, and diabetes. A strategy in the modulation of NO expression may be through the use of herbal medicines. We surveyed medicinal plant research that utilized multicomponent extracts similar to what is used in clinical phytotherapy or in commerce, for demonstrated effects on NO activity. SciFinder Scholar, Pubmed, Web of Science, and BIOSIS were searched to identify human, animal, <em>in vivo</em>, <em>ex vivo </em>or <em>in vitro</em> research on botanical medicines, in whole or standardized form, that act on nitric oxide activity. iNOS was the most frequently investigated enzyme system and this system was up-regulated by many plant extracts, including, <em>Chicorium intybus, Cocos nucifera, Echinacea purpurea, Euonymus alatus, Ixeris dentate, Oldenlandia diffusa, Rhinacanthus nasutus, and Sida cordifolia. Many plant extracts down-regulated iNOS, including Centella asiatica, Dichroa Febrifuga, Echinacea purpurea, Evolvulus alsinoides, Fagonia cretica, Ginkgo biloba, Mollugo verticillata, Lactuca indica, Lithospermum erythrorhizon, Pueraria thunbergiana, and Taraxacum officinale</em>. The eNOS system was stimulated by <em>Eucommia ulmoides, Sida cordifolia</em>, and <em>Thymus pulegioides while Fagonia cretica, Rubia cordifolia</em> and <em>Tinospora cordifolia </em>down-regulated nNOS. Given the activity demonstrated by many of these herbal medicines, the increasing awareness of the effects of nitric oxide on a wide variety of disease processes and the growing incidence of these conditions in the population, further study of medicinal plants on nitric oxide signaling may lead to novel therapies and further insight into human physiology.

Oral hygiene is important to the generality of the human healthcare system. For this, the antifungal activities of the aqueous and ethanol extracts of four medicinal plants of Jatropha curcas (stem), Eucaluptus golbulus (leaves), Vernonia amygdalina (stem) and Zanthoxylum zanthoxyloides (root) were carried out in vitro against three species of Candida associated with oral thrush namely C. albicans, C. glabrata, C. tropicalis using the disc diffusion agar assay. The zones of inhibition varied with the test organisms as well as the extracts. The ethanolic extract of Jatropha curcas showed the highest zone of inhibition of 10.88 ± 0.22 mm against C. albicans while the least zone of inhibition (6.13 ± 0.13 mm) was exhibited by the ethanol extract of Z. zanthoxyloides on C. glabrata. The preliminary phytochemical screening showed the presence of tannin, saponin, alkaloids, flavonoids and reducing sugar in all plant samples. This study can be further used as a foundation for the screening of phytochemical constituents by pharmaceuticals for the control and eradication of oral thrush.

Background: The use of medicinal plants for general wellbeing and disease treatment is a common practice among tribal communities of Kokrajhar districts of Assam. However, little works have been done to study the pharmacological aspect of the plants. Objectives: The present study intends to study the antioxidant and antiproliferative properties of selected medicinal plants used by the tribal communities of Kokrajhar district of Assam since ancient times. Methods: Five traditionally important medicinal plants namely, Cassia fistula, Citrus grandis, Lindernia crustacea, Sacciolepis myosuroides, and Zingiber zerumbet were investigated for antioxidant, antiproliferative (cytotoxic) and apoptosis-inducing potential in the malignant cancer cell line. Phytochemical content such as phenolic and flavonoid content were estimated following standard protocol. The methanolic extract of plants were investigated following phosphomolybdate method (TAC), FRAP, DPPH, ABTS, and TBARS assays. Antiproliferative activities of the plants were carried out by MTT assay in DL and PBMC cells. The apoptotic study was carried out following the acridine orange and ethidium bromide staining method and fluorescent microscopic imaging. Based on the significant (P≤0.05) high apoptotic inducing potential of the plant and to further dissect the molecular mode of action including downstream biological action, major phytochemicals derived from L. crustacea were investigated for its prospective binding affinity with antiapoptotic cancer target proteins. Results: Antioxidant studies by FRAP, DPPH, ABTS, and TBARS assay revealed that all the five plants contain considerable free radical scavenging activity. C. fistula showed the strongest free radical scavenging activity while the fruit peel extract of C. grandis showed poor activity. The overall antioxidant activities of plants such as TAC, FRAP, DPPH, ABTS, and TBARS may be arranged in decreasing activity as C. fistula > Z. zerumbet > L. crustacea > S. myosuroides > C. grandis. MTT based cell proliferation study showed that all the plants extract significantly (P≤0.05) inhibited cell viability with negligible cytotoxicity (~5-12%) in normal cells. Moreover, L. crustacea showed promising antiproliferative and apoptosis-inducing ability against Dalton’s lymphoma. It is worth mentioning that the major bioactive compounds of the most potent plant extract, L. crustacea interacted with anti-apoptotic proteins (cancer target) with higher affinity and the results are compared with reference inhibitors. Conclusion: It is worth noting that these plants have the potential to consider for further scientific studies in different cell lines and animal models. Furthermore, isolation and characterization of bioactive compound(s), may promise the discovery of new and valuable drugs candidate to tackle various human diseases.

Warm and cold water extracts were prepared from the 17 dried plant species and tested in vitro in the scratch assay with NIH 3T3 fibroblasts from mice. The wound healing scratch assay was used to evaluate the effect of the plants on cell proliferation and/or migration in vitro, as a test for potential wound healing properties. After 21 hours of incubation increased proliferation and/or migration of fibroblasts in the scratch assay was obtained for 5 out of the 17 plant species. HPLC separation of the most active plant extract, which was a warm water extract of Philenoptera cyanescens, revealed the wound healing activity to be attributed to rutin and a triglycoside of quercetin. The present study suggests that Allophylus spicatus, Philenoptera cyanescens, Melanthera scandens, Ocimum gratissimum, and Jasminum dichotomum have wound healing activity in vitro.

Chlamydia spp. are intracellular pathogens of humans and animals that cause a wide range of diseases such as blinding trachoma and sexually transmitted infections. According to the World Health Organization (WHO), there are more than 127 million new infections each year worldwide. Chlamydial urogenital infections can cause cervicitis, urethritis, pelvic inflammatory disease and infertility. From within an intracellular niche, termed an inclusion, the Chlamydiae complete their life cycle shielded from host defenses. The host cell defense response used to eliminate the pathogen must subvert this protective shield and is thought to involve the gamma interferon-inducible family of immunity related GTPase proteins and nitric oxide. Typically, azithromycin and doxycycline are the first line drugs for the treatment of chlamydial infections. Although C. trachomatis is sensitive to these antibiotics in vitro, currently, there is increasing bacterial resistance to antibiotics including multidrug-resistant C. trachomatis, which have been described in many instances. Therefore, alternative drug candidates against Chlamydia should be assessed in vitro. In this study, we tested and quantified the activity of plant extracts against Chlamydia-infected HeLa cells with C. trachomatis inclusions. The in vitro results show that post-treatment with Artemisia inculta Delile extract significantly inhibits Chlamydia infection compared to DMSO-treated samples. In conclusion, plant extracts may contain active ingredients with antichlamydial activity potential and can be used as alternative drug candidates for treatment of Chlamydia infection which has significant socio-economic and medical impact.

Multidrug-resistant Mycobacterium tuberculosis strains have rapidly become a global health concern. North American First Nations communities have used traditional medicines for generations to treat many pulmonary infections. In this study, we evaluated the antimycobacterial activity of 5 medicinal plants traditionally used as general therapeutics for pulmonary illnesses and specifically as treatments for tuberculosis. Aqueous extracts of Aralia nudicaulis , Symplocarpus foetidus , Heracleum maximum , Juniperus communis, and Acorus calamus were screened for antimycobacterial activity against Bacillus Calmette–Guérin, Mycobacterium avium, and M. tuberculosis H37Ra using the colorimetric microplate resazurin assay. Extracts of Acorus calamus and H. maximum root demonstrated significant antimycobacterial activity comparable to that of the rifampin control (2 µg/mL). Evaluation of the cytotoxicity of these 2 extracts using the MTT assay also showed that the extracts were less toxic to 3 human cell lines than was the DMSO positive control. This study demonstrates that aqueous extracts of the roots of H. maximum and Acorus calamus possess strong in vitro antimycobacterial activity, validates traditional knowledge, and provides potential for the development of urgently needed novel antituberculous therapeutics.

The use of medicinal plant extracts and their isolated bioactive compounds for the management of diabetes mellitus has been tremendously increased in recent decades. The present study aimed at providing in-depth information on medicinal flora that has been widely used in the Sri Lankan traditional healthcare system for the management of diabetes mellitus. The data of this review article were obtained from published articles from January 2000 to September 2020 in scientific databases of PubMed, Web of Science, and Google Scholar. In this review, a total number of 18 medicinal plants with the antidiabetic activity were expressed, and their isolated antidiabetic active compounds were highlighted as new drug leads. Results of the reported studies revealed that medicinal plants exert a potent antidiabetic activity via both in vitro and in vivo study settings. However, bioactive compounds and antidiabetic mechanism (s) of action of many of the reported medicinal plants have not been isolated/elucidated the structure in detail, to date. Reported antidiabetic medicinal plants with other properties such as antioxidant and antihyperlipidemic activities deliver new entities for the development of antidiabetic agents with multiple therapeutic targets. This is a comprehensive review on potential antidiabetic activities of the Sri Lankan medicinal plants that have been widely used in the traditional healthcare system. The information presented here would fill the gap between the use of them by traditional healers in the traditional medicine healthcare system in Sri Lanka and their potency for development of new drug entities in future.

In Argentina, there are numerous native species which are an important source of natural products and which are traditionally used in medicinal applications. Some of these species are going through an intense extraction process in their natural habitat which may affect their genetic diversity. The aim of this study was to establish vegetative propagation systems for three native forestal species of medicinal interest. This will allow the rapid obtainment of plants to preserve the germplasm. This study included the following species which are widely used in folk medicine and its applications: Erythrina crista-galli or “seibo” (astringent, used for its cicatrizant properties and for bronchiolitic problems); Acacia caven or “espinillo” (antirheumatic, digestive, diuretic and with cicatrizant properties) and Salix humboldtiana or “sauce criollo” (antipyretic, sedative, antispasmodic, astringent). The methodology included the micropropagation of seibo, macro and micropropagation of Salix humboldtiana and the somatic embryogenesis of Acacia caven. The protocol for seibo regeneration was adjusted from nodal sections of seedlings which were obtained from seeds germinated in vitro. The macropropagation through rooted cuttings of “sauce criollo” was achieved and complete plants of this same species were obtained through both direct and indirect organogenesis using in vitro cultures. The somatic embryogenesis for Acacia caven was optimized and this led to obtain a high percentage of embryos in different stages of development. We are able to support the conservation of native forest resources of medicinal use by means of vegetative propagation techniques.

The efficient production of plant-derived medicinal compounds (PDMCs) from in vitro plants requires improvements in knowledge about control of plant or organ development and factors affecting the biosynthesis pathway of specific PDMCs under in vitro conditions, leading to a realistic large-scale tool for in vitro secondary metabolite production. Thus, this study aimed to develop an in vitro technique, through the induction and proliferation of calli, for production of plant fresh weight, and to compare the PDMC profile obtained from the plants versus in vitro calli of Phyllanthus amarus. It was successfully possible to obtain and proliferate two types of calli, one with a beige color and a friable appearance, obtained in the dark using Murashige and Skoog (MS) medium plus 2,4-dichlorophenoxyacetic acid (2,4-D), and a second type with a green color, rigid consistency, and nonfriable appearance obtained under light conditions and MS medium plus 6-benzyladenine (6-BA). In vitro micropropagated plants that gave rise to calli were also acclimatized in a greenhouse and cultivated until obtaining the mass for PDMC analysis and used as a control. While the micropropagated-derived plants concentrated the lignans niranthin, nirtetralin, and phyllanthin, the Phyllanthus amarus calli proliferated in vitro concentrated a completely different biochemical profile and synthesis of compounds, such as betulone, squalene, stigmasterol, and β-sitosterol, in addition to others not identified by GC-MS database. These results demonstrate the possibility of applying the calli in vitro from Phyllanthus amarus for production of important PDMCs unlike those obtained in cultures of differentiated tissues from field plants.

The use of plants in traditional medicine become very common nowadays throughout the world and in developing countries in particular. The current study was carried out aiming to evaluate the cytotoxicity of Mallotus oppositifolius (Geisel.) Müll.-Arg (Euphorbiaceae) and Enantia polycarpa (DC) Engl. and Diels (Annonaceae) two medicinal plants mostly used for human traditional medicine to treat diarrhea in Côte d’Ivoire on Human Foreskin Fibroblast (HFF) cells. These plants were selected after ethno-botanical investigations in southern Côte d’Ivoire. Therefore, The results proved that the ethanolic extract of Enantia polycarpa showed the biggest yield (56,4%). The 70 % éthanolic extract of Mallotus oppositifolius is not cytotoxic at 1000 µg / ml concentration, but mitogen. Our study has shown that the ethanolic extract of Mallotus oppositifolius stimulates HFF cells (131% of viability confluents cells and 156% of viability cells in division). While Enantia polycarpa seems cytotoxic on HFF cells at 1000 µg / ml concentration (36% of viability confluents cells and 55% of viability cells in division). The study revealed that the moderate use of these medicinal plants only represents a limited risk of toxicity.

Objective: The objective of the present work is to study the in vitro anti-inflammatory and antioxidant activity of medicinal plants. The extent and correlation between anti-inflammatory and antioxidant activity have been studied.Method: Methanolic and aqueous extracts of five medicinal plants, namely, Ficus racemosa, Aloe vera, Cannabis sativa, Datura stramonium, and Calotropis gigantean have been taken for in vitro anti-inflammatory and total antioxidant activity.Result: The study showed that the inhibition of protein (albumin) denaturation was maximum in aqueous extract of A. vera with 97.55±1.45%. Proteinase inhibitory action of different plant extracts showed significant action and was found to be maximum in aqueous extract of D. stramonium with 87.89±2.58%. Heat-induced hemolysis showed that maximum inhibition was with aqueous extract of F. racemosa with 90.72±3.33%. When hypotonicity-induced hemolysis activity was done it was found maximum in methanolic extract of C. gigantea with 90.58±3.04%. Anti-lipoxygenase activity was found maximum in methanolic extract of F. racemosa with 94.05±4.24%. When total antioxidant activity was done, it was found highest in F. racemosa (4.38±0.546 mM equivalent of ascorbic acid/g tissue).Conclusion: An overall strong positive correlation between anti-inflammatory and antioxidant activity was observed, indicating that antioxidant activity of the plant species studied might be responsible for their anti-inflammatory property. Further work needs to be undertaken to fully elucidate the antioxidants responsible for anti-inflammatory action and to develop better herbal drug formulations.

Abstract- The aim of this work is to study the inhibitory effect of some Moroccan medicinal plants: parsley, nettle, oregano and corn beard on the crystallization of oxalocalcium urinary stones under experimental conditions which simu l a t e t h e u ri n a r y e n v ir o nme n t (physiological concentrations in calcium and oxalate, temperature and pH). The experimental tests were followed by the turbidimetric method using UV-Visible Model SP8-400 spectrophotometry, the response of which restores the concentration of calcium oxalate. The results showed that the potassium and magnesium ions which constitute the main elements of these plants compete with the calcium ions in order to combine with the oxalate ions. All the competitive reactions reflecting the affinities of the different ions towards each other contribute to the observed overall inhibition of the crystallization of calcium oxalate.

Full textAbstract:
Up to 60% of South Africans consult traditional healers for treatment of diseases, including sexually transmitted diseases (STDs). Medicinal plants play a major role in the treatment of STDs by traditional healers, but without any scientific support. During this study, five plants were chosen from literature due to their reputed use by traditional healers in the treatment of STDs. The plants were screened for anti-bacterial and anti-STD activity. The plants chosen were Clematis brachiata, Elephantorrhiza elephantina, Lepidium bonariense, Ranunculus multifidus and Typha capensis. The STD screening was conducted with Candida albicans, Neisseria gonorrhoeae and Haemophilus ducreyi. Bacillus subtilus, Micrococcus luteus, Staphylococcus aureus, Enterobacter sp., Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Aspergillus niger were also included for screening purposes. Only Lepidium bonariense possesses activity against all the organisms tested. It is thus clear that a need exists to determine the efficacy of medicinal plants and that the obtained information is communicated to the traditional healers.

Hexane, ethyl acetate, ethanol and methanol extracts of Psidium guajava, Terminalia chebula, Mimusops elengi and Achyranthes aspera were tested against the dental caries causing bacteria Streptococcus mutans and fungus Candida albicans isolated from caries infected patients. All the four extracts of P. guajava showed activity against both S. mutans and C. albicans. Maximum zone of inhibition was observed in ethyl acetate of P. guajava. The four extracts of T. chebula and M. elengi showed antibacterial activity against S. mutans. M. elengi extracts and ethanol extract of T. chebula did not show any antifungal activity against C. albicans. Except for the hexane extract of A. aspera, the other three extracts showed activity against the tested microbes. The ethyl acetate P. guajava leaf extract showed the minimum inhibitory concentration (MIC) against S. mutans to be <0.076 mg/mL in both MHB and BHI. The P. guajava ethyl acetate extract was subjected to GC-MS.
