Flavonoids from Some Frullania Species (Hepaticae)

Abstract

Abstract From Frullania teneriffae 5 known flavone aglycones and 6 flavone glycosides were isolated, among them the new 6-OH-luteolin-6-O-β-ᴅ-glucoside-7-O-β-ᴅ-glucoside-6′′′-(3-hydroxy-3-methylglutaroylester). F. cesatiana contains 2 flavone-di-C-glucosides and the new 6-OH-luteolin-7-O-β-ᴅ-glucoside-6′′-(3-hydroxy-3-methylglutaroylester)-3′-O-glucuronide. The phenolic pattern of F. eboracensis was compared to that of F. muscicola. The known 6-OH-luteolin-7-O-β-ᴅ-glucoside-6′′-(3-hydroxy-3-methylglutaroylester) was identified from F. gibbosa and F. arecae.
