“…Despites rich literature about the plant, the chemistry and biology of T. articulata have yet to be thoroughly examined. For instance, the phytochemical screening of T. articulata cones methanolic extract has positively identified other classes of compounds such as alkaloids and saponosides ( Saber et al, 2021 ). Likewise, the individual compounds and their pharmacological effects have yet to be determined.…”

Tetraclinis articulata (vahl) masters: An insight into its ethnobotany, phytochemistry, toxicity, biocide and therapeutic merits

2022

Tetraclinis articulata (Vahl) Masters, commonly known as Sandarac tree and Araâr, is the only species representing the genus Tetraclinis Masters. The plant has been extensively used for medicinal, artistic, and ritual purposes since its first recorded use in 1800 B.C. Recently, a full range of ethnobotanical investigations has been undertaken to document the plant’s empirical knowledge. They reported the use of different parts, such as leaves, stems, cones, bark, and roots, as part of folk healing practices to manage diabetes mellitus, hypertension, fever, stomach disorders, and diarrhea, among others. The phytochemical studies have identified at least 130 compounds from leaves, cones, resin, bark, and woods. These chemical constituents are categorized into phenolic acids, flavonoids and their derivatives, volatile compounds, phytosterols, and fatty acids, among others. Furthermore, they have strongly been correlated with the promising antimicrobial, antioxidant, neuroprotective, antiurolithiatic, anti-inflammatory, antidiabetic, and cytotoxic properties of the plant. Toxicological studies argued that the plant is quite safe and devoid of eventual toxicity; however, in-depth investigations are required to validate the safety of the plant. The remarkable antimicrobial and antioxidant potencies of various extracts from the plant against a wide range of foodborne pathogens support their possible use to increase the shelf life of foodstuffs in the food industry. Likewise, various plant-based extracts have been proven to exert substantial biocidal properties, making them potential alternatives to synthetic pesticides in agriculture. The present review provides an up-to-date comprehensive insight about the ethnobotanical uses of T. articulata, along with its phytochemistry and biological activities to furnish directions for further studies. We also discussed the biocidal potency of the plant and highlighted its usage to extend the shelf life of perishable foods.

“…Aromatic plants currently present a reliable source of active ingredients known for their therapeutic properties, in particular, antioxidant activity (Saber et al, 2021). In this context, a study recently published under the theme, of ethnobotanical, phytochemical, and antioxidant study of fifty medicinal and aromatic plants, the results obtained can be considered as a source of information for scientific research in the field of pharmacology and phytochemistry.…”

Within the framework of the valorization of the medicinal and aromatic plants of Morocco, we were interested during this study in the characterization and the phytochemical identification of some secondary metabolites present in Mentha suaveolens Ehrh. and the evaluation of the antioxidant activity of this species using four methods: DPPH free radical scavenging test, 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid, (ABTS) radical cation scavenging test, FRAP test measuring antioxidant power, and β bleaching-carotene. Mentha suaveolens is a species belonging to the Lamiaceae family, harvested in southern Morocco, and widely used in traditional medicine for its biological properties attributed mainly to phenolic compounds. Just as they protect plants, secondary metabolites also have a protective role in the human body and are therefore beneficial to our health. They are attributed, in particular, with antioxidant, anti-inflammatory, and antibacterial properties. In this regard, characterization and identification tests of secondary metabolites revealed the presence of alkaloids, flavonoids, catechic tannins, and terpenes in this plant, whereas, the aerial parts of this species are devoid of coumarins, cyanogenic compounds, saponins and free quinones. The quantification of the phenolic compounds gave high contents, with contents of total phenols (54.75 ± 5.62) μg GAE/mg, total flavonoids (32.41 ± 0.41) μg QE/mg, and total condensed tannins (27 ± 1) μg CE/mg. In addition, the results obtained show that Mentha suaveolens extract has stronger antioxidant activity using the β-Carotene method with IC50 (0.24 ± 0.06) mg/mL against IC50 (0.021 ± 0.001) mg/mL for the standard antioxidant by the DPPH free radical scavenging test.

“…Currently, despite the development of modern medicine, aromatic plants remain a solid base that we cannot do without in our daily lives due to their various uses in different fields, as we have shown in this study for the three most used aromatic and medicinal plants by the rural population: Rosmarinus officinalis, Thymus vulgaris and Mentha pulegium. Importantly, the identification and quantification of secondary metabolites in different plant species is important for the discovery of new drugs and the development of herbal medicines, which is confirmed by earlier studies [25,29].…”

“…However, in the third year of our study, we observed a decline in essential oil production as the weather conditions continued to deteriorate for the sample of three plants. Additionally, other studies [24,25] have shown that the relative water content, chlorophyll index, and essential oil yield decreased under severe water deprivation. Moreover, Thymus vulgaris exhibited the highest yield of essential oil, followed by Rosmarinus officinalis, and finally Mentha pulegium.…”

The Impact of Environmental Stress on the Secondary Metabolites and the Chemical Compositions of the Essential Oils from Some Medicinal Plants Used as Food Supplements

This study aims to study the impact of environmental stresses on the chemical compositions of essential oils and the content of secondary metabolites of the plants most used by the rural population: Thymus vulgaris, Mentha pulégium and Rosmarinus officinalis. The results of the study indicate that the percentage of secondary metabolites increased in the second year when temperature and water pressure increased by 50%. Specifically, coumarin increased from 3.94% to 9.23%, saponins increased from 6.17% to 7.78%, tannins increased from 2.90% to 6.12%, alkaloids increased from 6.72% to 15.95%, and flavonoids increased from 7.42% to 12.90%. However, in the fourth year, the temperature continued to increase, and water availability decreased by 75%, leading to a decrease in the rate of secondary metabolites. Coumarin decreased from 9.22% to 6.15%, saponin decreased from 7.80% to 6.79%, tannin decreased from 6.11% to 4.16%, alkaloids decreased from 15.95% to 10.45%, and flavonoids decreased from 12.90% to 9.70%. Similar results were observed for the essential oil yield, which increased in year two from 3.57% to 3.84% and decreased in year four to 1.04%. The same pattern was observed for Mentha pulégium and Rosmarinus officinalis. The gas chromatography analysis of the three essential oil samples showed that the majority of the compounds of the three plants were modified under the conditions of climate change. For Mentha pulégium, pulegone was found to represent the highest proportion in sample two (73.3%), followed by sample one (71.1%), and finally, sample three (61.8%). For Rosmarinus officinalis, the majority of compounds were cineole and camphor, with cineole representing 36% in sample two, 45.89% in sample one, and 43.08% in sample three, and camphor representing 21.44% in sample two, 21.56% in sample three, and 17.44% in sample one. For Thymus vulgaris, the majority of the compounds were Thymol and Carvacrol, which underwent approximately the same modifications as the majority of compounds in the other two plants. The results indicate that environmental stresses can lead to significant changes in these compounds, which can affect the medicinal and aromatic properties of these plants. The findings of this study highlight the need for more research to understand the impacts of climate change on plant species and the potential implications for human health and well-being.
