Abstract:
The species Chiliadenus glutinosus (L.) Fourr. has a large number of therapeutic uses reported in the traditional Spanish medicine. The growing interest in preserving the ethnopharmacological knowledge related to the botanical diversity existing in Spain and the interest in achieving scientific validation of the therapeutic properties of medicinal species has led to the development of this study. To do it, all the known medicinal uses of Ch. glutinosus in Spain were compiled, then an exhaustive bibliographic research on its chemical composition was carried out, and finally, an in silico validation of the bioactive phytochemicals present in a higher proportion in the essential oil of Ch. glutinosus: camphor, borneol, lucinone, glutinone, quercetin, kutdtriol, and kaempferol; in an attempt to justify the reported traditional uses of the species. It was found that much of the traditional medicinal uses of Ch. glutinosus, along with the biological activity of its phytochemicals, are supported by scientific evidence. The results place this species in a prominent position to initiate possible lines of research to develop new, more effective drugs and improve therapies to treat conditions and diseases that affect the different organic systems of the human being.

Abstract:
Artemisia annua L. (Asteraceae) still represents the only source of artemisinin, considered as one of the most important drugs for the treatment of malaria and which, more recently, has been shown to be effective against numerous types of tumors. The foliage and inflorescence of A. annua also yield an essential oil upon hydrodistillation. This oil has been evaluated at different development stages (pre-flowering and flowering) by GC/MS. The volatile oil from plants at full blooming showed numerous constituents, with germacrene D (21.2%), camphor (17.6%), β-farnesene (10.2%), β-caryophyllene (9%), and bicyclogermacrene (4.2%) among the main ones. Aromatic waters, after extraction with n-hexane, showed the presence, among others, of camphor (27.7%), 1,8-cineole (14%), artemisia ketone (10.1%), α-terpineol (6.1%), trans-pinocarveol (5.4%), and artemisia alcohol (2%). From plants at the pre-flowering stage, aromatic waters were obtained with camphor (30.7%), 1,8-cineole (12.8%), artemisia alcohol (11.4%), artemisia ketone (9.5%), alpha-terpineol (5.8%), and trans-pinocarveol (3.0%) as the main constituents. The qualitative and quantitative profiles of the two aromatic waters were similar. These results permitted the conclusion to be made that A. annua could be harvested a long time before the onset of flowering to obtain higher yields of artemisinin or could be allowed to attain maturity to obtain valuable yields of volatiles.

Abstract:
The amount and chemical composition of essential oils are crucial for the modulation of the flavor, scent and therapeutic properties of aromatic and medicinal plants. The aim of this study was to evaluate the effects of phenology and weather conditions on the essential oil yield obtained from the aerial parts of Salvia lavandulifolia Vahl. Besides, we tried to carry out an approach to the chemical composition at the time of full bloom. Essential oil production of several accessions was monitored throughout the whole phenological cycle, both, at the original location growing wild and at the experimental plot as cultivated plants. Local pedoclimatic conditions seem to be crucial for the plant essential oil production. Our results showed high conditioning rates from both yearly climatic conditions and developmental stage of the plants. Maximum yield production was reported at the full seed maturation stage (average 1.74%) and after a slight dry period (average 2.16%). Phytochemical differences were maintained when plants were forced to grow under common pedoclimatic conditions. Thereby, essential oil analysis showed some populations formed by clearly distinct individuals while others had more homogenous plants. Compounds such α-pinene, β-pinene + myrcene, limonene, 1,8-cineol, camphor and β-caryophyllene were the main compounds of the essential oils of S. lavandulifolia.

Abstract:
The chemical compositions have been investigated of the volatile oils of nine populations of six species from Albania, namely Artemisia absinthium, Calamintha nepeta, Hypericum perforatum, Sideritis raeseri subsp. raeseri, Origanum vulgare subsp. hirtum from two wild populations, and Salvia officinalis (sage) from two wild and one cultivated population,. The essential oils were obtained by hydrodistillation and their analyses were performed by GC–MS. The major constituents were: A. absinthium: neryl isovalerate (19.5%), geranyl isobutanoate (16.4%) and carvacrol (8.8%); C. nepeta: pulegone (31.7%), spathulenol (20.0%) and isomenthone (12.7%); H. perforatum: caryophyllene oxide (31.0%), δ-selinene (10.5%) and carvacrol (10.4%); O. vulgare: carvacrol (81.0, 78.6%), γ-terpinene (5.5, 7.1%) and p-cymene (4.9, 4.1%) for O. vulgare originating from Tepelena and Vlora, respectively; S. raeseri: carvacrol (36.7%), caryophyllene oxide (17.8%), β-caryphyllene (8.7%), spathulenol (7.7%) and myrtenol (6.4%); S. officinalis: camphor (40.2, 47.8, 45.9%), α-thujone (19.2, 22.2, 13.7%), eucalyptol (5.4, 2.6, 6.0%), camphene (5.8, 6.1, 3.9, %), borneol (2.1, 2.9, 5.7%) and bornyl acetate (3.3, 1.4, 5.6%) for samples originating from Tepelena, Tirana and Vlora, respectively. The essential oils were also tested for their free radical scavenging activity using the following in vitro assays: i) interaction with the free stable radical of DPPH (1,1-diphenyl-2-picrylhydrazyl), and ii) inhibition of linoleic acid peroxidation with 2,2'-azobis-2-methyl-propanimidamide, dihydrochloride (AAPH). Finally, their inhibitory activity toward soybean lipoxygenase was evaluated, using linoleic acid as substrate. The essential oil of O. vulgare (OV-VL) presented the highest interaction with the stable radical DPPH (76.5%), followed by that of A. absinthium (54.7%). O. vulgare (OV-TP) and A. absinthium showed high anti-lipid peroxidation activity, 97.5% and 96.5%, respectively, higher than that of the reference compound trolox (73.0%). Only the tested sample of O. vulgare (OV-VL) significantly inhibited soybean lipoxygenase (54.2%).

Abstract:
The current pandemic caused by SARS-CoV-2 has led to a massive change in every aspect of our lives. It has grossly affected the healthcare system, business and world trade, disruption of movement and supply of essential goods and has crippled the global economy. Although few vaccines have been approved for the control of disease, targeted therapy options for this virulent disease still remain limited and elusive. Exhaustive search for potent therapeutic candidate is in progress, for which herbal armory are also being explored. Medicinal plants and their products play a vital role in alleviating various diseases and have been reported to exhibit a wide range of biological activities. Plant-based drugs with antiviral, anti-inflammatory and immunomodulotry activities were hypothetically considered as potential drugs to prevent and mitigate the prevailing situation caused by SARS-CoV-2. Arq Ajīb ‘a Unani formulation’ presents compelling approach in treating numerous diseases. The ingredients of Arq Ajīb and their phytocompounds have been reported for wide-ranging pharmaco-biological activities including antiviral, anti-inflammatory, immunomodulotry, anti-allergic, antitussive and bronchodilatory activities. Scientific data available on the formulation ingredients and their phytocompounds indicates that the formulation may have a significant role in augmenting the immune status of individual, protecting them from infection and providing symptomatic relief to patients affected with COVID-19. Hence, it may be considered as a potential drug for the development of novel therapeutic candidate for SARS-CoV-2 infection. This multi-faceted review highlights the therapeutic significance and pharmacological actions of Arq Ajīb and its ingredients to demonstrate the plausible role of the formulation in combating COVID-19.

Abstract:
Volatile components of essential oils from the leaves and stems of Croton jacobinensis, C. rhamnifolius, C. muscicapa and C. micans, which are medicinal plants found in the Caatinga biome of northeastern Brazil, were analyzed using GC and GC/MS. The acaricidal activity of these oils against Tetranychus urticae was evaluated using the fumigation method. Oil yields from the Croton species ranged from 1.1±0.0 to 0.6±0.0%, w/w, for leaves and 0.7±0.0 to 0.1±0.0% for stems. Sesquiterpenoids were dominant in all oils, except the stem oil from C. rhamnifolius, which exhibited a high monoterpene content, and the leaf and stem oils from C. muscicapa, which were rich in phenylpropanoids. The major volatile components of the leaf and stem oils from C. jacobinensis were ( Z)-α-atlantone (24.3±0.4%) and trans-isolongifolanone (22.8±0.5%), respectively. The most abundant constituents detected in C. rhamnifolius were #aL-cedrene epoxide (23.3±0.1%) and caryophyllene oxide (21.9±0.0%) in the leaf oil, and camphor (16.6±0.5%) and tricyclene (12.8±0.1%) in the stem oil. Foenicolin was the main compound identified in the leaf (50.6±0.2%) and stem (72.7±0.6%) oils of C. muscicapa, while α-bulnesene (32.9±0.2%) and guaiol (17.9±0.7%) were the principal components of C. micans oils. These oils exhibited a high degree of toxicity in the fumigation assay. The stem oils from C. jacobinensis and C. rhamnifolius exhibited high lethality rates, with LC50 values of 0.3 and 0.2 μL/L of air after 24 h, respectively. The results suggest the potential use of stem essential oil, especially from C. rhamnifolius and C. jacobinensis, for the integrated control of Tetranychus urticae.

Abstract:
This review paper highlights the recent updates of the fragrant camphor tree (Cinnamomum camphora) and camphor oil is used as a medicine for controlling many human diseases, relief of pain, inflammation and irritation in the body and skin. It can also be very effective in treating and preventing some serious, life threatening diseases. Recently medicinal plants (sweet worm wood; Artemisia annua) containing camphor essential oil has been tested against corona virus (SARS-CoV-2) disease (Covid-19). Commercially, camphor is very important with many biological properties and is used as a topical ointment since camphor is a very toxic substance and oral consumption of camphor should be avoided.
