Four flavan-3-ol glycosides and three proanthocyanidin glycosides have been isolated from the fern, Davallia divaricata, together with procyanidins B-1 and B-2 and a trimeric procyanidin.All of these glycosides have been shown to possess an allopyranose moiety.The structures were elucidated on the basis of chemical and spectroscopic evidence. Key Word Index-Davallia divaricata; Davalliaceae; fern; flavan-3-ol; proanthocyanidins; allosides; procyanidins; condensed tannin.
