摘要：

Two new monoterpene glycosides named bidensmenthosides A, B and a new (+)-jasmololone glucoside, were isolated from the air-dried whole plant of Bidens parviflora Willd. Their structures were determined as ( 1S, 3S, 4R)-3-hydroxy-p-menth-6-one3-O-beta-D-glucopyranoside (1), (3R, 4R)-3-hydroxy- p- menth- 1 ( 2)-en-6-one 3-O-beta-D-glucopyranoside (2) and (4R)- hydroxy-3-methyl-2-(2 Z- pentenyl)-cyclopent-2enone 4-O-beta-D-glucopyranoside (3) based on spectroscopic analysis and physiochemical properties, respectively. The bidensmenthosides A, B and aglycone of 3 were found to reduce 2, 2- diphenyl- 1-picrylhydrazyl ( DPPH) radicals.
