Abstract
Four flavan-3-ol glycosides and three proanthoeyanidin 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.
