Cannabinoids are important chemotaxonomic markers unique to Cannabis. Previous studies show that a plant's dry-weight ratio of Δ(9)-tetrahydrocannabinol (THC) to cannabidiol (CBD) can be assigned to one of three chemotypes and that alleles B(D) and B(T) encode alloenzymes that catalyze the conversion of cannabigerol to CBD and THC, respectively. In the present study, the frequencies of B(D) and B(T) in sample populations of 157 Cannabis accessions were determined from CBD and THC banding…

Characterisation of cannabinoid composition in a diverse Cannabissativa L. germplasm collection
It is proposed that in order to carry out comprehensive screening of genetic resource collections and to identify chemotypic variants specific for end-use pharmacological applications, a strategy which adopts both cannabinoid profiling and the co-dominant DNA marker assay is required.

The inheritance of chemical phenotype in Cannabis sativa L. (III): variation in cannabichromene proportion
The mechanism that controls the proportion of cannabichromene (CBC), a potential pharmaceutical, in the cannabinoid fraction of Cannabis sativa L. is explored and the ability of PJC plants to enable the production of pharmaceutical raw material with high CBC purity is demonstrated.
THC and CBD Fingerprinting of an Elite Cannabis Collection from Iran: Quantifying Diversity to Underpin Future Cannabis Breeding
The data showed that Iran can be considered a new region of high potential for distribution of cannabis landraces with diverse THC and CBD content, predominantly falling into three groups, as Type I = THC-predominant, Type II = approximately equal proportions of CBD (both CBD and THC in a ratio close to the unity), and Type III = CBD-Predominant.
Identification of Terpenoid Chemotypes Among High (-)-trans-Δ9- Tetrahydrocannabinol-Producing Cannabis sativa L. Cultivars.
Abstract Introduction: With laws changing around the world regarding the legal status of Cannabis sativa (cannabis) it is important to develop objective classification systems that help explain the
Chemotyping and Determination of Antimicrobial, Insecticidal, and Cytotoxic Properties of Wild-Grown Cannabis sativa from Nepal
The essential oil from Nepalese Cannabis sativa was screened for antimicrobial, cytotoxic, larvicidal, and insecticidal activity, and it appears as though C. sativa is relatively non-toxic.
Cannabinoids and Terpenes as Chemotaxonomic Markers in Cannabis
In this paper, we present principal component analysis (PCA) results from a dataset containing 494 cannabis flower samples and 170 concentrate samples analyzed for 31 compounds. A continuum of
Cannabinomics: Application of Metabolomics in Cannabis (Cannabis sativa L.) Research and Development
Cannabis research is still in its infancy, and it is highly foreseen that the employment of advanced metabolomics will provide insights that could assist the sector to face the aforementioned challenges.
Industrial hemp (Cannabis sativa L.) as a possible source of cannabidiol
(-)-Cannabidiol (CBD) is a cannabinoid, which has unique pharmacological and biological activities.The aim of this study was to determine the CBD, cannabidiolic (CBDA), and canabigerolic acids (CBGA)
The inheritance of chemical phenotype in Cannabis sativa L. (II): Cannabigerol predominant plants
B0 is considered as a member of the BD allelic series encoding a CBD synthase isoform with greatly weakened substrate affinity and/or catalytic capacity, and is plausible that this B0 is a mutation of normally functional BD.


The inheritance of chemical phenotype in Cannabis sativa L.
Four crosses were made between inbred Cannabis sativa plants with pure cannabidiol (CBD) and pure Delta-9-tetrahydrocannabinol (THC) chemotypes, and it is suggested that codominance is due to the codification by the two alleles for different isoforms of the same synthase, having different specificity for the conversion of the common precursor cannabigerol into CBD or THC.
Cannabinoid level in the leaves as a tool for the early discrimination of Cannabis chemiovariants.
Cannabinoid patterns in seedlings of Cannabis sativa L. and their use in the determination of chemical race
The cannabinoid contents of seedlings from twelve strains of Cannabis of known chemical race showed that the true leaves of the THC type contained a relatively high content of THC and also contained cannabichromene (CBC), sometimes as the major cannabinoid, whereas the CBD type had much lower amounts of THCand no CBC; CBD being the major component.
Qualitative and Quantitative Aspects of the Inheritance of Chemical Phenotype in Cannabis
A segregation analysis of the different F2 progenies obtained showed that chemotype, estimated as CBD/THC ratio, behaves as a qualitative character, and a model for a single locus B, with two co-dominant alleles, B D and B T is described.
Cannabinoid content of individual plant organs from different geographical strains of Cannabis sativa L.
An attempt to compare cannabinoid profiles of specific plant organs from several strains and clones of Cannabis to determine whether cannabinoid variability exists in different organs and during different phases of organ development and whether variability, if present, influences the phenotypic classification of the plant.
It is emphasized that glands of Cannabis represent a dynamic system within the cannabinoid synthesizing activities of this plant and that glandular trichomes are prominent features on the shoot system of Cannabis saliva L.
Cannabinoid Phenotypes in Cannabis sativa
IT has been suggested that “drug” strains and “non-drug” strains of Cannabis sativa L. comprise two comprehensive groups1,2, which can be identified on the basis of their relative content of two of
Purification and Characterization of Cannabidiolic-acid Synthase from Cannabis sativa L.
It is concluded that CBDA is predominantly biosynthesized from cannabigerolic acid rather than cannabinerolic acid, although the kcat for the former is lower than that for the latter, and that the enzymatic cyclization does not proceed via oxygenated intermediates.
Flavonoid variation in Cannabis L.
The distribution of compounds supported the subspecific treatment of the genus suggested by Small & Cronquist (1976), but the data were less helpful in resolving trends amongst the varieties recognized by those authors.
Characterisation of Cannabis accessions with regard to cannabinoid content in relation to other plant characters
Variation within populations for cannabinoid content, and consistency of chemical characters at the population level were investigated and various combinations of cannabinoid content and other economic plant characters were observed, thus a breeding programme will not be hampered by strict linkage.
