Abstract:

In the present study, we have phytochemically characterized 5 different abundant Aloe species, including Aloe vera (L.) Burm.f., using silylation followed by Gas Chromatography-Mass Spectrometry technique and compared the data using multivariate statistical analysis. The results demonstrated clear distinction of the overall phytochemical profile of A vera, highlighted by its divergent spatial arrangement in the component plot. Lowest correlation of the phytochemical profiles were found between A vera and A aristata Haw. (−0.626), whereas highest correlation resided between A aristata and A aspera Haw. (0.899). Among the individual phytochemicals, palmitic acid was identified in highest abundance cumulatively, and carboxylic acids were the most predominant phytochemical species in all the Aloe species. Compared to A vera, linear correlation analysis revealed highest and lowest correlation with A aspera ( R2 = 0.9162) and A aristata ( R2 = 0.6745), respectively. Therefore, A vera demonstrated distinct spatial allocation, reflecting its greater phytochemical variability.

Abstract:

Targeting inflammation and the pathways linking inflammation with cancer is an innovative therapeutic strategy. Tastants are potential candidates for this approach, since taste receptors display various biological functions, including anti-inflammatory activity (AIA). The present study aims to explore the power different tastes have to predict a phytochemical’s anti-cancer properties. It also investigates whether anti-inflammatory phytocompounds also have anti-cancer effects, and whether there are tastes that can better predict a phytochemical’s bivalent biological activity. Data from the PlantMolecularTasteDB, containing a total of 1527 phytochemicals, were used. Out of these, only 624 phytocompounds met the inclusion criterion of having 40 hits in a PubMed search, using the name of the phytochemical as the keyword. Among them, 461 phytochemicals were found to possess anti-cancer activity (ACA). The AIA and ACA of phytochemicals were strongly correlated, irrespective of taste/orosensation or chemical class. Bitter taste was positively correlated with ACA, while sweet taste was negatively correlated. Among chemical classes, only flavonoids (which are most frequently bitter) had a positive association with both AIA and ACA, a finding confirming that taste has predictive primacy over chemical class. Therefore, bitter taste receptor agonists and sweet taste receptor antagonists may have a beneficial effect in slowing down the progression of inflammation to cancer.

Abstract:

Background Insect-vectored Leishmania are responsible for loss of more disability-adjusted life years than any parasite besides malaria. Elucidation of the environmental factors that affect parasite transmission by vectors is essential to develop sustainable methods of parasite control that do not have off-target effects on beneficial insects or environmental health. Many phytochemicals that inhibit growth of sand fly-vectored Leishmania—which have been exhaustively studied in the search for phytochemical-based drugs—are abundant in nectars, which provide sugar-based meals to infected sand flies. Principle findings In a quantitative meta-analysis, we compare inhibitory phytochemical concentrations for Leishmania to concentrations present in floral nectar and pollen. We show that nectar concentrations of several flowering plant species exceed those that inhibit growth of Leishmania cell cultures, suggesting an unexplored, landscape ecology-based approach to reduce Leishmania transmission. Significance If nectar compounds are as effective against parasites in the sand fly gut as predicted from experiments in vitro, strategic planting of antiparasitic phytochemical-rich floral resources or phytochemically enriched baits could reduce Leishmania loads in vectors. Such interventions could provide an environmentally friendly complement to existing means of disease control.

Abstract:

Identification of wood species that are difficult to distinguish from their anatomical structure can be done through phytochemical (extractive substance) profiling. This research aimed to analyze the phytochemical profile as a sorter for three species of mangrove wood from Indramayu and Cilacap Regencies, Indonesia, using the liquid chromatography-mass spectrum. The phytochemical markers of taxonomic were the dominant compounds only found in one wood species. The results showed that the three types of wood are dominated by phytochemicals dissolved in ethanol. The results of LCMS analysis of the ethanol extract showed that the phytochemical markers were triterpenoid, flavonoid, and fatty acyls glycoside groups for Rhizophora apiculata, steroid and naphthalene groups for Bruguiera gymnorhiza, and alkaloid as well as fatty amide group for Bruguiera cylindrica. The dominant compounds that characterize these can be used in sorting between mangrove wood species. Keywords: characterizer, compound, mangrove, phytochemicals

Abstract:

A phytochemical-loaded nanoparticle is an important therapeutic agent that aids in enhancing the bioavailability of phytochemicals of lower water solubility and delivering the phytochemicals to the site of infection in a targeted manner. This strategy has also been developed for the management of COVID-19. They can be used as antiviral medication carriers, causing the direct death of viral particles and imitating the host in order to neutralize viral processes. In the formulation of phytochemical-loaded nanoparticles against SARS-CoV-2, different categories of nanoparticles, including inorganic, lipid-based, and polymeric nanoparticles, are used. Numerous phytochemicals belonging to the classes of alkaloids, flavonoids, terpenes, terpenoids, saponins, glycosides, polyphenols, and lignans, that demonstrate effective antiviral properties are utilized for the phytochemical-loaded nanoparticles. This approach results in increased solubility and stability of the phytochemicals with lower systemic toxicity, in addition to site-specific delivery. The combination therapy delivers multiple therapeutic agents at the site of infection. It can also be administered directly to the respiratory system by inhalation delivery. Therefore, this approach can potentially inhibit the application of phytochemical-loaded nanoparticles for the treatment of COVID-19, which is still in its replication of the SARS-CoV-2 virus and reduces the severity of the disease. The infancy and a number of obstacles must be overcome prior to their widespread use.

Abstract:

The geographical location of Morocco and the diversity of its topography ensure a high variability of climate conditions, ranging from humid to Saharan, and extending through subhumid, arid, and semi-arid stages. This variability offers a high floristic diversity, while the medical use of these phytochemicals has not been fully explored. Advanced computer-aided drug discovery utilizes chemical biology to accelerate the study of phytochemicals at the molecular level and discover novel therapeutic pathways. Currently, there is no online resource for phytochemicals in Morocco. Therefore, it is of interest to describe the Moroccan Phytochemicals Database (MPDB), accessible, featuring over 600 phytochemicals derived from journal articles and other reports. The web interface of the database, which is simple and easy to use, provides each phytochemical's reference, plant sources, 3D structures, and all related information. Furthermore, we provide direct links to commercially available analogs from Mcule. In addition, we provide the results of the first virtual screening against cardiovascular targets. We present these data to facilitate further exploration and exploitation of Morocco's rich phytochemical resources, and to contribute to the global understanding and application of these compounds in the medical and scientific communities.

Abstract:

Purple coneflower, Echinacea purpurea (L.) Moench, is an important phytomedicinal species, producing phenolics and alkamides which have medicinal properties. This study examined the contribution of arbuscular mycorrhizal (AM) colonization on the physiology and biochemistry of E. purpurea, alone or in combination with jasmonic acid (JA), and over time. It was hypothesized that AM colonization enhances growth, nitrogen assimilation and secondary metabolism in E. purpurea. It was also hypothesized that JA application alone, or in combination with AM colonization, and growth time increases the phytochemical content. To verify these hypotheses, three greenhouse experiments were performed with E. purpurea, with or without AM fungus, Glomus intraradices Schenck & Smith, and harvested after (1) 13 weeks of growth; (2) 13 weeks and JA treatment; and (3) five different growth periods starting from week four to fifteen. The overall results indicated that AM colonization significantly increased the mass of shoots and roots, the concentration of proteins in roots and most of the phenolics. Results also suggested that the effects of AM colonization and/or JA application are similar on the induction of phenolics. Furthermore, time was a main factor on the enhancement of the phytochemical content, of the alkamides found to be dominant in roots, and phenolics in shoots. Optimizing the growth by AM colonization represents an organic method of enhancing E. purpurea yield and phytochemical content.

Abstract:

Extracts from the root bark, stem bark, and leaves of R. natalensis were screened for antibacterial activity against standard bacterial strains
Staphylococcus aureas, Escherichia coli and Pseudomonas aureginosa, and fungi
Candida albicans, Trichophyton mentagrophytes or Microsporum gyseum. Chromatographic techniques were utilized to isolate pure compounds. This study validates and documents, in a systematic way, the antimicrobial properties of the R. natalensis used for many years by many people of the world. It also provides valuable information for
further phytochemical isolation and characterization studies of active compounds, necessary for the development of new drugs. The extractions were carried out using broad spectrum of solvents
(hexane, dichloromethane, ethyl acetate, and methanol). Fractionation was done using standard chromatographic techniques. A total of seven (7) compounds were isolated from R. natalensis.
Three of the isolates were characterized and their structures were unambiguously established by detailed spectroscopic analysis that involved high resolution mass spectrometry, 1D and
2D-NMR spectral data experiments 1H, 13C, DEPT, COSY, HMBC, and NOESY. These compounds are: 3-(1-(2,4-dihydroxyphenyl)-3,3-bis(4- hydroxyphenyl)-1-oxopropan-2-yl)-7-methoxy- 4H-chromone-4-one (39), Rhuschromone, a
novel compound isolated for the first time, 2&rsquo

&rsquo
,4&rsquo

- trihydroxychalcone (40) and 3-((Z)-heptadec-13-enyl) benzene- 1,2-diol (41), an urushiol. Compound 39 recorded the highest activity zone of inhibition (21mm) against S. aureas, which was found to be 50% as active the chloramphenicol standard used. The
traditional use of the extracts in infections and inflammatory conditions is rationalized based on the content of theisolated compounds, and it has been proposed that the total crude extract, with its
contents of so many bioactive compounds, could be formulated for use in many infections, microbial or fungal. Furthermore, not all of the species studied to date have been fully characterized
for potential bioactivities. Thus, there remains a significant research gap spanning the range from lead chemical discovery through process development and optimization in order to better
understand the full bioactive potential of many of these plants.

Abstract:

There is a long history of use and modern commercial importance of large (Vaccinium macrocarpon Aiton) and small cranberries (V. oxycoccus L. and V. vitis-idaea L.) in North America. While epidemiological research indicates cranberries have positive health benefits, identifying specific phytochemicals for disease prevention remains elusive. The central objective of this research was to develop phytochemical characterization tools for comparing commercially cultivated cranberries and two wild-harvested Vaccinium species. A method was developed and validated to quantify cyanidin-3-O-galactoside (C3Ga), cyanidin-3-O-glucoside (C3Gl), cyanidin-3-O-arabinoside (C3Ar), peonidin-3-O-galactoside (P3Ga) and peonidin-3-O-arabinoside (P3Ar) in cranberry fruit products. The relative standard deviation (%RSDr) of anthocyanins ranged from 1.77% to 3.31% with the method detection limit (MDL) for C3Ga, C3Gl, C3Ar, P3Ga, and P3Ar estimated at 0.018, 0.016, 0.006, 0.013, and 0.011 µg/mL, respectively. In biological replicates of V. macrocarpon cultivars, anthocyanin content (mg/g) was determined to be 7.98±5.83 in Ben Lear; 7.02±1.75 in Bergman; 6.05± 2.51 in GH1; 3.28± 1.88 in Pilgrim and 2.81 ±0.81 in Stevens. V. oxycoccus contained the five major anthocyanins with the ratio of glycosylated peonidins to cyanidins varying from V. macrocarpon. V. vitis-idaea contained no measurable glycosylated peonidins. Determination and statistical analysis of serotonin, melatonin and ascorbic acid content in the three Vaccinium species, found only vitamin C positively correlated with antioxidant activity. Metabolome comparisons made from untargeted metabolomics by ultra-fast liquid chromatography (UFLC) with time-of-flight (TOF) mass spectrometry (MS), found different pools of common metabolites extracted in methanol (7635), 70% ethanol (5832), and water (5664). Each cranberry matrix contained unique compounds; fruit=3680, product 1=3464, product 2=3500. Clustering was visualized using principal component and partial least squares discriminate analyses with application of univariate statistics to mitigate false discoveries. A significance algorithm found 1987, 716 and 1556 compounds (p-value<0.05) in methanol, 70% ethanol and water extracts, respectively. In metabolomic profiles of V. macrocarpon varietals 6481 compounds were conserved and 136 (Ben Lear), 84 (Bergman), 91 (GH1), 128 (Pilgrim) and 165 (Stevens) unique observations were made. Across the three Vaccinium species 8000-10,000 phytochemicals were detected with 4624 compounds conserved between them. Together these data establish targeted and untargeted methods for phytochemical characterization of cranberries, providing foundational chemotaxonomic knowledge and new insights into the maintenance of health in traditional North American diets.

Abstract:

Advancement in plant cell culture technology has permitted the increasing interest in harvesting plant metabolites from cell cultures. This technique is based on in vitro propagation of plant callus which contains many beneficial compounds under sterile conditions as the plant source or raw material for natural product extraction. In vitro production of plant sources acknowledges; conservation of plant species in natural habitats which has been a global issue due to over harvesting of medicinal plants for the natural products manufacturing and production of phytochemicals, independent from seasonal and environmental limitations. Establishment of cell cultures is challenging. The main aim is to establish cell cultures as the starting material for the phytochemical analysis in Rumex Vesicarius.

Abstract:

Phytochemical screening was conducted on Hylocereusundatus foliage to determine the presence of alkaloids, flavonoids, tannins, and saponins using methanol and chloroform solvents via oven-dried and open air-dried methods. As for the antioxidant activity, powdered Hylocereusundatus foliage were extracted using both solvents through Ferric Reduction Antioxidant Power (FRAP) assay; and the findings were then compared to 2,2-Diphenyl-1-Ipicrylhydrazyl (DPPH) assay from previous studies. Results revealed that for both methods in phytochemical screening, flavonoids were present only in methanol extract; however, saponins were present in both extracts. No alkaloid and tannins were present in both extracts using both methods. Antioxidant activity results revealed that the methanol extract (59.05%) and chloroform extract (20.58%) using the FRAP assay were comparable to that of DPPH assay in which methanol extract (88.81%) and chloroform extract (38.30%) were obtained. It concludes that Hylocereusundatus has comparable phytochemical constituents and antioxidant activity based on the different drying and assay methods.

Full text

Abstract:

Although phytochemicals are plant-derived toxins that are primarily produced by plants as a form of defense against insects or microbes, several lines of studies have demonstrated that phytochemicals (e.g., polyphenols, carotenoids, and amino acids) have several beneficial biological actions for human health, such as anti-oxidative, anti-inflammatory, and cardioprotective effects. Recent studies have demonstrated that phytochemicals can modulate neuronal excitability in the nervous system, including nociceptive sensory transmission, so it is possible that phytochemicals could be complementary alternative medicine candidates; specifically, therapeutic agents against pain. The focus of this review is to elucidate the mechanisms underlying the modulatory effects of phytochemicals on neuronal electrical signals, such as generator potentials, action potentials, and postsynaptic potentials, in the nociceptive pathway neurons resulting in potential local anesthetic effects, intravenous anesthesia and analgesic effects, and inflammatory pain relief effects. In addition, we discuss the contribution of phytochemicals to the relief of nociceptive and/or pathological pain and their potential clinical application on the basis of our recent studies in vivo.

Abstract:

Original Objectives Specific objectives are to: (1) modify charge and hydrophobicity of pectins to improve emulsion stabilizing properties (2) develop emulsions that can be sterically stabilized using modified pectins and/or pectin/protein hybrids (3) obtain submicronal inner emulsion droplets (10-50 nanometers) with small and monodispersed double emulsion (1-2 μm) droplets with long-term stability (possibly by emulsified microemulsions) and (4) trigger and control the release at will. Background Methodology for encapsulation and controlled release of selected addenda, e.g. drugs, vitamins, phytochemicals, flavors, is of major impact in the food industries. Stable double emulsions with desired solubilization and release properties of selected addenda are formed using charge modified pectin or pectin-protein hybrids. Major conclusions, solutions, achievements * We developed methodology to isolate PME isozymes and prepared modified pectins in sufficient quantity to characterize, form single and double emulsions and test stability. *Amino acid sequence of PME isozymes was estimated and will facilitate cloning of PME for commercial application * The contribution of total charge and distribution of charge of modified pectin was determined *Soluble complexes or modified pectins and whey isolates are formed * Stable W/O/W double emulsions were formed that did not cream, had small particle size * Inner phase of double emulsions are nano-sized and stable. These new structures were termed emulsified microemulsions (EME) * Release of bioactives were controlled between a few days to months depending on layering on droplets by hybrids * Commercial testing by Israeli company of stability and release of Vitamin C showed good chemical stability Implications Resolved the major stability limitation of W/O/W emulsions. Resolved the questions regarding citrus PMEs and tailored pilot scale modification of pectins.
