[Structure determination of three saponins from the stem bark of Albizzia julibrissin Durazz].
Three new saponins named Julibroside J1, J2 and J3 were isolated from the stem bark of Albizzia julibrissin Durazz (Albizziae Cortex). Based on chemical and spectral methods, e.g. 1H- and 13C-NMR, DEPT, COSY CH-COSY, TOCSY, HMQC-COSY, HMQC-TOCSY, NOESY, HMBC, their structures have been identified as; Julibroside J1 (one triterpene, nine sugars, two monoterpenes I); Julibroside J2(one triterpene, eight sugars two monoterpenes II); Julibroside J3(one triterpene, nine sugars two monoterpenes III).
