Abstract

From the fronds of Dennstaedtia distenta, new flavan-3-ol(catechin) derivatives, distenin(1), its dimer(2)and its trimer (3), were isolated in addition to vitexin. On the basis of the spectroscopic and chemical evidence, their structures were established as (2R, 3R)-flavan-3,5,7-triol(1), distenin-(4β→8)-distenin(2)and distenin-(4β→8)-distenin-(4β→8)-distenin(3), respectively.
