Cannabinoid levels of individual mature glandular trichomes from two clones and two strains of Cannabis sativa L., which included both drug and fiber phenotypes, were investigated by gas‐liquid chromatographic analyses. Capitate‐stalked glands were selectively harvested from vein and nonvein areas of pistillate bracts while capitate‐sessile glands were harvested from these areas of leaves. The qualitative cannabinoid profile characteristic of the strain or clone was maintained in the individual capitate‐stalked glands while the quantitative cannabinoid profiles varied with each strain or clone and between vein and nonvein areas as well. Capitate‐sessile glands were found to contain conspicuously lower levels of cannabinoids than capitate‐stalked glands. This study emphasizes that glands of Cannabis represent a dynamic system within the cannabinoid synthesizing activities of this plant.
