- Abstract
[Objectives] This study was conducted to study the chemical constituents from Laportea bulbifera. [Methods] The 60% ethanol extract from L. bulbifera was isolated and purified by silica, Sephadex LH-20, ODS, semi -preparative HPLC and recrystallization. Their chemical structures were elucidated by physicochemical properties and spectroscopic methods. [Results] These compounds were determined as kaempferol-3-O-a-L- (3-0-acetyl) -rhamnoside-7-0-a-L-rhamno-side (1), sutchuenoside A (2), kaempferol-3-O-[|3-D-glucopyranosyl-(1^3)] -ct-L-(4-0-acetyl) -rhamnopyranoside-7-O-ct-L-rhamnopyr anoside (3). Compounds 1 -3 are isolated from genus Laportea for the first time. Compound 3 is a new compound. [Conclusions] This study lays a foundation for improving the quality standard of L. bulbifera and the development and utilization of its resources.
