Chemotaxonomic Features Associated with Flavonoids of Cannabinoid-Free Cannabis (Cannabis sativa subsp. sativa L.) in Relation to hops (Humulus Lupulus L.)

Abstract

The major flavonoids present in the leaves and flowers of the cannabinoid-free cannabis (Cannabis sativa subsp. sativa L.) cultivars Felina and Futura are orientin (1), vitexin (2), luteolin-7-O-g-D-glucuronide (3), and apigenin-7-O-g-D-glucuronide (4), while prenylated flavonoids, to which the potent estrogenicity of hops (Humilus lupulus L.) is associated, are absent. The different composition of flavonoids has chemotaxonomic value.
