title: [Chemical constituents from barks of Nothopanax delavayi].
abstract: Eleven compounds were isolated and purified from the barks extract of Nothopanax delavayi and their structures were identified as serratagenic acid-3-O-alpha-L-arabinopyranosyl-28-O-beta-D-glucopyranosyl ester (1), serratagenic acid-3-0-alpha-L-arabi-nopyranosyl-28-O-[alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl] ester (2), serratagenic acid (3), serratagenic acid-3-O-alpha-L-arabinopyranoside (4), serratagenic acid-beta-O-beta-(2', 4'-O-diacetyl) -D-xylopyranosyl-28-O-[alpha-L-rhamnopy-ranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->46)-beta-D-glucopyranosyl] ester (5), serratagenic acid-3-O-alpha-(4'-O-acetyl)-L-arabino pyrano-syl-28-0- [-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl] ester(6), serratagenic acid-3-O-alpha-(2'-O-acetyl)-L-arabinopyranosyl-28-O-[-alpha-L-rhamnopyranosyl- (1-->4) -beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl] ester(7), serratagenic acid-3-0-beta-D-xylopyranosyl-28-O-[-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl] ester (8), protocatechuic acid (9), ethyl caffeate (10) and caffeic anhydride (11) by physicochemical properties and spectroscopic data analysis. Among them, compounds 3-4 and 9-11 were firstly isolated from the genus Nothopanax, and compounds 5-8 were isolated from this plant for the first time.
