[Isolation and structural identification of phenylethanoid glycosides from Corallodiscus flabellata].
OBJECTIVE
To study the chemical constituents from Corallodiscus flabellata.


METHODS
The compounds were isolated and purified by macroporous adsorption resin, silica gel column chromatography and identified on the basis of their physiochemical and spectral data.


RESULTS
Three phenylethanoid glycosides (I-III) were obtained from the n-BuOH fraction of water-extracts. Their structures were elucidated as 3,4-dihydroxyphenylethanol-8-O-[beta-D-apiofuranosyl (1-->3)]-beta-D-glucopyranoside (I), 3,4-dihydroxyphenylethanol-8-O-[4-O-trans-caffeoyl-beta-D-apiofuranosyl (1-->3)-beta-D-glucopyranosyl-(1-->6)]-beta-D-glucopyranoside (II) and 3,4-dihydroxyphenylethanol-8-O-[beta-D-apiofuranosyl(1-->3)-beta- D-glucopyranosyl-(1-->6)]-beta-D-glucopyranoside (III).


CONCLUSIONS
Compounds I, II and III are new compounds.
