摘要
从合欢皮（Ａｌｂｉｚｚｉａｅｃｏｒｔｅｘ）的９５％乙醇提取物的正丁醇萃取部分中分离得到３个新的三萜皂甙，用化学方法及１Ｈ和１３ＣＮＭＲ，ＤＥＰＴ，ＣＯＳＹ，ＴＯＣＳＹ，ＨＭＱＣＣＯＳＹ，ＨＭＱＣＴＯＣＳＹ，ＨＭＢＣ，ＮＯＥＳＹ等波谱方法鉴定其结构为：Ｉ（１个三萜，９个糖，２个单萜），命名为合欢皂甙（ｊｕｌｉｂｒｏｓｉｄｅ）Ｊ１；ＩＩ（１个三萜，８个糖，２个单萜），命名为合欢皂甙Ｊ２；ＩＩ（１个三萜，９个糖，２个单萜），命名为合欢皂甙Ｊ３。
Three new saponins named Julibroside J 1, J 2 and J 3 were isolated from the stem bark of Albizzia julibrissin Durazz ( Albizziae Cortex ). Based on chemical and spectral methods, e.g 1H and 13 C NMR, DEPT, COSY CH COSY, TOCSY, HMQC COSY, HMQC TOCSY, NOESY, HMBC, their structures have been identified as; Julibroside J 1 (one triterpene, nine sugars, two monoterpenes I); Julibroside J 2 (one triterpene, eight sugars two monoterpenes II); Julibroside J 3 (one triterpene, nine sugars two monoterpenes III).
