Chemical Studies on Bryophytes. 21. Flavonoid Glycosides of Hedwigia ciliata.

Abstract
Six flavonoid O-glycosides and 1 C-glycosides were identified from the moss H. ciliata. Four of the O-glycosides are now natural products: 1 apigenin tetraglycoside and 3 triglycosides of apigenin and luteolin. The others are 2 earlier known apigenin and luteolin diglycosides. The C-glycoside is an apigenin 6,8-di-C-hexoside. The structures were determined using spectroscopic methods, sugar linkage analysis by GLC and hydrolytic experiments.
