摘　　要：目的:研究掌叶苹婆Sterculia foetida的化学成分。方法:通过各种柱色谱进行分离纯化,根据理化性质和波谱数据进行结构鉴定。结果:分离并鉴定了8个化合物:5,7,8-三羟基-4′-甲氧基黄酮-8-O-β-D-葡萄糖苷(1),5,7,8-三羟基-4′-甲氧基黄酮-7-O-β-D-葡萄糖苷(2),槲皮素-3-O-β-D-葡萄糖苷(3),芹菜素-6,8-二葡萄糖碳苷(4),葛根素(5),5,7,8,3′-四羟基-4′-甲氧基黄酮(6),5,7,8-三羟基-3′,4′-二甲氧基黄酮(7),5,7,8-三羟基-4′-甲氧基黄酮(8)。结论:化合物1,2,4～8为首次从掌叶苹婆中分离得到。Objective：To study the chemical constituents from the leaves of Sterculia foetida. Method：Compounds were isolated by chromatographic techniques. Their structures were elucidated by spectroscopic methods. Result：Eight compounds were identified as 5,7,8-tetrahydroxy-4＇-methoxyflavone-8-O-β-D-glucoside （1）,5,7,8-tetrahydroxy-4＇-methoxyflavone-7-O-β-D-glucoside（2）,quercetin-3-O-β-D-glucoside （3）,apigenin-6,8-di-C-β-D-glucoside （4）,puerarin （5）,5,7,8,3＇-tetrahydroxy-4＇-methoxyflavone （6）,5,7,8-tetrahydroxy-3＇,4＇-dimethoxyflavone （7）,5,7,8-tetrahydroxy-4＇-methoxyflavone （8）. Conclusion：Compounds 1,2 and 4-8 were isolated from this plant for the first time.
