Abstract
Individual plant organs from different geographical strains of Cannabis saliva L. were analyzed for their cannabinoid content by gas-liquid chromatography. Analyses showed that different plant parts from each strain varied quantitatively in their cannabinoid content. However, each plant part possessed a cannabinoid profile which characterized the chemical phenotype of that strain. Accumulation of a specific cannabinoid in high quantities that was uncharacteristic of that strain was found. Factors such as maturity of plant organ, sex of the plant, location of the plant organ on the plant and sampling procedures influenced the accumulation of cannabinoids. Pollen grains and seeds (intact or crushed) were found to lack detectable levels of cannabinoids. Based on these results, precautions that should be taken when accumulating data on the chemical phenotype of a Cannabis plant are discussed.
