Three new C-flavonoids from Corallodiscus flabellata.
Three new C-glycosylflavones, named 5,7,4'-trihydroxy-6-methoxy-8-C-[beta-D-xylopyranosyl- (1 --> 2)]-beta-D-glucopyranosyl flavonoside (1), 5,7,4'-trihydroxy-8-methoxy-6-C-[beta-D-xylopyranosyl-(1 --> 2)]-beta-D-glucopyranosyl flavonoside (2), and 5,3',4'-trihydroxy-7,8-dimethoxy-6-C-[beta-D-xylopyranosyl-(1 --> 2)]-beta-D-glucopyranosyl flavonoside (3), along with two known compounds 5,4'-dihydroxy-7-methoxy-6-C-glucopyranosyl-flavonoside (4), 3-methoxy-4-hydroxymethyl benzoate (5) were isolated from 70% acetone extract of Corallodiscus flabellata. Their structures were identified on the basis of spectroscopic techniques and chemical methods.
