Cannflavins are a group of chemical compounds found in Cannabis sativa.[1] Chemically, they are prenylflavonoids and are unrelated to THC and other cannabinoids. Cannflavins A and B were first identified in the 1980s and cannflavin C was identified in 2008.[2]

Because cannflavins A and B are inhibitors of prostaglandin E2 production in vitro,[1][3] the cannflavins have been studied for their potential use as anti-inflammatory agents.[4]

Cannflavins A and B are biosynthesized by prenylation of chrysoeriol.[5]
