“…THCAS and CBDAS levels in trichomes in flowers were described as stable during the latter stages of floral development in the C . sativa strain Bediol [ 43 ]. These authors also reported higher levels of THCAS and CBDAS in leaves versus flowers or flower trichomes, which is quite the inverse of the results reported here for four separate strains of Cannabis (Figs 7 and 8 ).…”

There has been an increased use of medical Cannabis in the United States of America as more states legalize its use. Complete chemical analyses of this material can vary considerably between producers and is often not fully provided to consumers. As phytochemists in a state with legal medical Cannabis we sought to characterize the accumulation of phytochemicals in material grown by licensed commercial producers. We report the development of a simple extraction and analysis method, amenable to use by commercial laboratories for the detection and quantification of both cannabinoids and terpenoids. Through analysis of developing flowers on plants, we can identify sources of variability of floral metabolites due to flower maturity and position on the plant. The terpenoid composition varied by accession and was used to cluster cannabis strains into specific types. Inclusion of terpenoids with cannabinoids in the analysis of medical cannabis should be encouraged, as both of these classes of compounds could play a role in the beneficial medical effects of different cannabis strains.

“…The resin inside glandular trichomes of C. sativa, the apoplast of glandular scales in R. dauricum, and oil bodies in R. marginata are the storage environments and sites of the oxycyclase-catalyzed last step in the synthesis of cannabinoids [5,37,40,97]. 1 H NMR-based metabolomics of C. sativa trichomes revealed co-storage of the cannabinoids with an abundance of sugars, amino acids, choline, organic acids, and terpenes [5]. Sugars, choline, and organic acids are typical constituents that, when present in appropriate stoichiometric ratios, form natural deep eutectic solvents (NADESs) [139].…”

Phytocannabinoids are bioactive natural products found in some flowering plants, liverworts, and fungi that can be beneficial for the treatment of human ailments such as pain, anxiety, and cachexia. Targeted biosynthesis of cannabinoids with desirable properties requires identification of the underlying genes and their expression in a suitable heterologous host. We provide an overview of the structural classification of phytocannabinoids based on their decorated resorcinol core and the bioactivities of naturally occurring cannabinoids, and we review current knowledge of phytocannabinoid biosynthesis in Cannabis, Rhododendron, and Radula species. We also highlight the potential in planta roles of phytocannabinoids and the opportunity for synthetic biology approaches based on combinatorial biochemistry and protein engineering to produce cannabinoid derivatives with improved properties. Phytocannabinoids The term phytocannabinoid (see Glossary, also cannabinoid) defines meroterpenoids with a resorcinyl core typically decorated with a para-positioned isoprenyl, alkyl, or aralkyl side chain [1]. The alkyl side chain typically contains an odd number of carbon atoms, where orcinoids contain one carbon, varinoids three, and olivetoids five. Cannabinoids with an even number of carbon atoms in the side chain are known but rare. The term cannabinoid generally refers to molecules with a characteristic chemical structure; however, the term may also refer to pharmacological ligands of human endocannabinoid receptors [2]. In this review we use the chemical definition of cannabinoids. Phytocannabinoids occur in flowering plants, liverworts, and fungi (Figure 1, Key Figure). They were first isolated from Cannabis sativa L. (Cannabaceae), a plant with a long and controversial history of use and abuse [3]. The mammalian brain has receptors that respond to compounds found in C. sativa. Accordingly, these receptors were named cannabinoid receptors (CB x) and are the basis of the endocannabinoid system. Studies in human and animals demonstrated that the endocannabinoid system regulates a broad range of biological functions, including memory, mood, brain reward systems, and drug addiction, as well as metabolic processes such as lipolysis, glucose metabolism, and energy balance [2]. More than 113 different cannabinoids have been isolated from C. sativa and these are classified into distinct types: cannabigerols (CBGs), cannabichromenes (CBCs), cannabidiols (CBDs), (−)-Δ 9-trans-tetrahydrocannabinols (Δ 9-THCs), (−)-Δ 8-trans-tetrahydrocannabinols (Δ 8-THCs), cannabicyclols (CBLs), cannabielsoins (CBEs), cannabinols (CBNs), cannabinodiols (CBNDs), cannabitriols (CBTs), and the miscellaneous cannabinoids (Figure 2) [4]. C. sativa predominantly produces alkyl type cannabinoids that carry a monoterpene isoprenyl moiety (C10) and a pentyl side chain (C5) [1]. The most abundant constituents are trans-Δ 9-THC, CBD, CBC, and CBG, together with their respective acid forms (Δ 9-THCA, CBDA, CBCA, and CBGA) [5]. Cannabinoid biosynthetic pathways ty...

“…NMR is recognized as an untargeted powerful tool [19,20] to give a complete metabolite profile of biological matrixes. Up to now, the NMR based metabolomic investigations regarding C. sativa L. have been focused on the study of plant tissues such as trichomes [21], cell suspensions [22] and inflorescences [23]. Only a partial assignment of the inflorescence NMR spectra is available in literature [23,24].…”

The chemical composition of the inflorescences from four Cannabis sativa L. monoecious cultivars (Ferimon, Uso-31, Felina 32 and Fedora 17), recently introduced in the Lazio Region, was monitored over the season from June to September giving indications on their sensorial, pharmaceutical/nutraceutical proprieties. Both untargeted (NMR) and targeted (GC/MS, UHPLC, HPLC-PDA/FD and spectrophotometry) analyses were carried out to identify and quantify compounds of different classes (sugars, organic acids, amino acids, cannabinoids, terpenoids, phenols, tannins, flavonoids and biogenic amines). All cultivars in each harvesting period showed a THC content below the Italian legal limit, although in general THC content increased over the season. Citric acid, malic acid and glucose showed the highest content in the late flowering period, whereas the content of proline drastically decreased after June in all cultivars. Neophytadiene, nerolidol and chlorogenic acid were quantified only in Felina 32 cultivar, characterized also by a very high content of flavonoids, whereas alloaromadendrene and trans-cinnamic acid were detected only in Uso-31 cultivar. Naringenin and naringin were present only in Fedora 17 and Ferimon cultivars, respectively. Moreover, Ferimon had the highest concentration of biogenic amines, especially in July and August. Cadaverine was present in all cultivars but only in September. These results suggest that the chemical composition of Cannabis sativa L. inflorescences depends on the cultivar and on the harvesting period. Producers can use this information as a guide to obtain inflorescences with peculiar chemical characteristics according to the specific use.
