“…In 1942, the low boiling point terpene fraction of Egyptian hashish contained two monoterpene hydrocarbons: p-cymene (205) and small quantities of 1-methyl-4-isopropenylbenzene or dehydro-p-cymene (208) [95]. Almost twenty years later, an acyclic monoterpene, myrcene (202) and the monocyclic monoterpene limonene (209), were identified in the essential oil of fresh, wild C. sativa from Canada [96].…”

Cannabis sativa is one of the oldest medicinal plants in the world. It was introduced into western medicine during the early 19th century. It contains a complex mixture of secondary metabolites, including cannabinoids and non-cannabinoid-type constituents. More than 500 compounds have been reported from C. sativa, of which 125 cannabinoids have been isolated and/or identified as cannabinoids. Cannabinoids are C21 terpeno-phenolic compounds specific to Cannabis. The non-cannabinoid constituents include: non-cannabinoid phenols, flavonoids, terpenes, alkaloids and others. This review discusses the chemistry of the cannabinoids and major non-cannabinoid constituents (terpenes, non-cannabinoid phenolics, and alkaloids) with special emphasis on their chemical structures, methods of isolation, and identification.

“…Cannabis stilbenoids can be divided into three main types based on their structure: phenanthrenes, dihydrostilbenes, and spiroindans (Figure 2). These components have been isolated from the cannabis stem, leaves and flower heads [31][32][33][34][35]. Despite their association with disease resistance and human health [36,37], only a few cannabis stilbenoids have been described in the literature with properties that may be beneficial to human health.…”

Extraction of Phenolic Compounds and Terpenes from Cannabis sativa L. By-Products: From Conventional to Intensified Processes

2021

Cannabis sativa L. is a controversial crop due to its high tetrahydrocannabinol content varieties; however, the hemp varieties get an increased interest. This paper describes (i) the main categories of phenolic compounds (flavonoids, stilbenoids and lignans) and terpenes (monoterpenes and sesquiterpenes) from C. sativa by-products and their biological activities and (ii) the main extraction techniques for their recovery. It includes not only common techniques such as conventional solvent extraction, and hydrodistillation, but also intensification and emerging techniques such as ultrasound-assisted extraction or supercritical CO2 extraction. The effect of the operating conditions on the yield and composition of these categories of phenolic compounds and terpenes was discussed. A thorough investigation of innovative extraction techniques is indeed crucial for the extraction of phenolic compounds and terpenes from cannabis toward a sustainable industrial valorization of the whole plant.

Reagents containing vanillin or anisaldehyde in ethanolic/H2S04 [15] gave very good results, with the vanillin reagent judged to be slightly better.…”

Various chromogenic chemical tests for Cannabis were evaluated as stains for the microscopical identification of the glandular trichomes of Cannabis sativa. Only vanillin in ethanolic sulphuric acid gave results comparable with the staining obtained with Fast Blue B. The specificity of these two stains was examined using 222 non-Cannabis species from 21 selected plant families. None of the species possessed glandular trichomes which stained with Fast Blue B. Two Mentha and three Callicarpa species had stained glandular trichomes with the vanillin reagent. It is concluded that Fast Blue B is a very specific stain for the cannabinoids in the glandular trichomes of C. sativa L.
