摘　　要：Six compounds have been isolated from the leaves of Pyrenacantha staudtii, two of which are new compounds. The new compounds have been characterized as kaempherol 3-O-β-rhamnopyranosyl (1→6)-β-D-glucopyranoside (1) and 4-β-glucopyranosyl-(2-furyl)-5-methy-l,2-glucopyranoside phenylmethanone (2). The known compounds are 3-pyridinecarboxylic acid (3), β-sitosterol (4), sitosterol 3-O-β-glucopyranoside (5) and taraxerol (6). Their structures were determined by spectroscopic and chemical evidences. The two new compounds together with 3-pyridinecarboxylic acid showed significant in vitro xanthine oxidase inhibitory activity. To the best of our knowledge, this is the first report of these compounds from this plant. 关键词：化合物药用植物氧化酶化学分析
