Abstract
Three anthocyanins were isolated from the acidified methanolic extract of blue flowers of Vicia villosa Roth (hairy vetch) by a combination of ion-exchange resin and gel filtration. Mostly on the basis of homo- and heteronuclear two-dimensional nuclear magnetic resonance techniqu es, their structures were elucidated to be the O-alpha-rhamnopyranosid e-5-O-beta-glucopyranosides of petunidin (71%), delphinidin (12%), and malvidin (9%), respectively.
