摘要
Reversed-phase HPLC coupled with electrospray MS has been used for the simultaneous separation and determination of flavonoid metabolites in leaves of Cyclanthera pedata, an edible Peruvian plant mainly used in South America for its anti-inflammatory, hypoglycaemic and hypocholesterolaemic properties. The flavonoid content of the leaves of C. pedata was compared qualitatively and quantitatively with that of the fruits. The isolation and structural characterisation by MS and NMR of two new minor components of the fruits, namely, 6-C-fucopyranosyl-(3-malonyl)-chrysin and 6-C-fucopyranosyl-(4-malonyl),-chrysin, are described.
