Abstract:
Isolation of eucannabinolide, its 3-isovaleroyl analog and pectolinarigenin from Schkuhria virgata (La Llave et Lex.) DC. is reported. The identity of eucannabinolide, which exhibits in vivo antileukemic activity, with ‘hiyodorilactone A’, ‘20-hydroxychromolaenide’ and ‘schkuhrin I’ is discussed.
