RESUMEN
For more than a century, Cannabis was considered a narcotic and has been banned by lawmakers all over the world. In recent years, interest in this plant has increased due to its therapeutic potential, in addition to a very interesting chemical composition, characterized by the presence of an atypical family of molecules known as phytocannabinoids. With this emerging interest, it is very important to take stock of what research has been conducted so far on the chemistry and biology of Cannabis sativa. The aim of this review is to describe the traditional uses, chemical composition and biological activities of different parts of this plant, as well as the molecular docking studies. Information was collected from electronic databases, namely SciFinder, ScienceDirect, PubMed and Web of Science. Cannabis is mainly popular for its recreational use, but it is also traditionally used as remedy for the treatment of several diseases, including diabetes, digestive, circulatory, genital, nervous, urinary, skin and respiratory diseases. These biological proprieties are mainly due to the presence of bioactive metabolites represented by more than 550 different molecules. Molecular docking simulations proved the presence of affinities between Cannabis compounds and several enzymes responsible for anti-inflammatory, antidiabetic, antiepileptic and anticancer activities. Several biological activities have been evaluated on the metabolites of Cannabis sativa, and these works have shown the presence of antioxidant, antibacterial, anticoagulant, antifungal, anti-aflatoxigenic, insecticidal, anti-inflammatory, anticancer, neuroprotective and dermocosmetic activities. This paper presents the up-to-date reported investigations and opens many reflections and further research perspectives.
RESUMEN
The chemical composition and inâ vitro biological activities of the essential oil (EO) of Micromeria macrosiphon Coss. and M.â arganietorum (J. Emb.) R. Morales, two Lamiaceae endemic to south Morocco, were investigated. GC/MS analysis resulted in the identification of 36 metabolites from the EO of M.â macrosiphon, 45 from M.â arganietorum. Borneol was the major metabolite in both oils and together with related derivatives such as camphor, accounted for 2/3 of the EO of M.â macrosiphon, 1/3 of those of M.â arganietorum. Pinene and terpinene derivatives were also present in high proportions. From a chemotaxonomic point of view, the composition of the examined samples may be related to those of other species endemic to Macaronesia. Both EOs showed significant toxicity towards liver HepG2 and melanoma B16 4A5 tumor cell lines at 100â µg/mL; however, they were also cytotoxic towards S17 normal cell lines, with a selectivity index <1. No antibacterial activity was noticed against 52 strains at 100â µg/mL.

ETHNOPHARMACOLOGICAL RELEVANCE: The argan [Argania spinosa (L.) Skeels] is one of the most important floristic resource in Morocco, it is the only representative of the Sapotaceae family and Argania genus found in Morocco. This tree is fully exploited by the native populations for nutrition, medication and cosmetics. The argan oil extracted from seed is the main tree product for his large use. AIM OF THE REVIEW: This review describes the traditional uses, chemical composition and biological activities of different the argan tree parts. MATERIALS AND METHODS: This review covers the literature available from 1972 to 2021. The informations were collected from electronic databases Scopus, PubMed, Web of Science, SciFinder and Google Scholar. RESULTS: Argan oil have been used for nutrition, and to treat several diseases, namely rheumatisms, hypercholesterolemia, atherosclerosis, lung infections, newborn gastrointestinal disorders, diabetes, skin and hair hydration. The other parts of Argan tree have been used to treat intestinal disorders, dermatosis, and hair caring, with additional uses such as livestock nutrition, carpentry and heating. The argan oil is primarily composed of unsaturated fatty acids mainly oleic and linoleic acids furthermore the chemical composition, of the others part, are very diversified (flavonoids, terpenoids, triacylglycerols, saponins. ). Diverse biological activities have been reported for argan oil, such as antioxidant, skin water retention, hair protection, cholesterol stabilization, antidiabetic, anticancer and antibacterial. Antimicrobial activities have been reported for argan leaves essential oils, when the fruit pulp organic extract presented very interesting antioxidant activity due to the presence of polyphenols. The argan cake is the seed waste produced during the extraction process, it is traditionally used for skin care and for livestock nutrition. Different biological activities of argan cake have been cited essentially antioxidant, haemoprotective, anti-inflammatory and antimicrobial.

ETHNOPHARMACOLOGICAL RELEVANCE: The genus Thymus is among the most important genera in the Lamiaceae family with 215 species and is widely distributed globally, mainly in the Mediterranean region. The genus contains many medicinal plants used in traditional Moroccan medicine for a long time in treating diverse diseases. AIM OF THE REVIEW: This review describes the traditional uses, biological activities and chemical composition of essential oils (EOs) obtained from Thymus species growing in Morocco. MATERIALS AND METHODS: Information related to the traditional uses, essential oils chemical composition and biological activities on Moroccan Thymus species were obtained using the electronic databases Web of science, Scopus, SciFinder, Pubmed and Google Scholar. RESULTS: Moroccan Thymus species have been used in treatment of several diseases, namely diabetes, digestive, circulatory, genital, nervous, urinary, skin and respiratory diseases. Diverse biological activities of Moroccan Thymus species EOs have been reported, such as antibacterial, antifungal, antioxidant, anti-proliferative, anti-tumoral, insecticidal, larvicidal, nematicide, anti-inflammatory, anti-cyanobacterial and anti-acetylcholinesterase. The chemical compositions of Thymus EOs is primarily composed of monoterpenes.

The chemical composition and inâ vitro antibacterial and cytotoxic activities of the essential oil (EO) of Chiliadenus antiatlanticus (Emb. & Maire) Gómiz, an asteraceous species endemic to the southwest of Morocco, were investigated. The EO yield was 1.07±0.28 %, twenty-seven metabolites were identified representing more than 96.4 % of the total composition. Camphor (35.7 %) and derivatives, borneol (4.9 %) and camphene (4.2 %) together with intermedeol (19.9 %), α-pinene (15.5 %) and (E)-pinocarveol (4.1 %) were the major constituents. An antibacterial activity was noticed against 24â strains (all Gram-positive) out of 71 at MICs values=100â µg/mL. The EO also showed significant toxicity towards liver HepG2 (55.8 % of cell viability) and melanoma B16 4A5 (41.6 % of cell viability) tumor cell lines at 100â µg/mL.
