摘要
从云南西双版纳的小叶臭黄皮（Ｃｌａｕｓｅｎａ ｅｘｃａｖａｔａ Ｂｕｒｍ．ｆ．）中分离到一个新黄酮甙，５，７，５’－三羟基－３’，４’－二甲氧基黄酮３－Ｏ－ａ－Ｌ－吡喃鼠李糖甙（１）和４个已知黄酮甙，分别为５，７，３’，５’－四羟基－４’－甲氧基黄酮３－Ｏ－ａ－Ｌ－吡喃鼠李糖甙（２），５，７，３’－三羟基－４’－甲氧基黄酮３－Ｏ－ａ－Ｌ－吡喃鼠李糖甙（３），５，７，４’－三羟基－３’，５’－二甲氧基黄酮３－Ｏ－ａ－Ｌ－吡喃鼠李糖甙（４），５，７，４’－三羟基黄酮３－Ｏ－ａ－Ｌ－吡喃鼠李糖甙（５）。根据ＨＭＱＣ、ＨＭＢＣ实验修正了化合物２～５Ｃ６和Ｃ８位碳化学位移的归属。
A new flavonoid glycoside,3', 4'-dimethoxy-5,7,5'-trihydroxyl-flavone 3-O-a-l -rhamnopyranoside(1) and four known flavonoid glycosides were isolated from the aerial part of Clausena excavata (Rutaceae),collected from Xishuangbanna,Yunnan,P R China.The 13 C NMR assignments for the C6 and C8 of the four known compounds 2-5 were revised by means of 2D NMR experiments.
