从木麻黄（Momordiacochinchinensis）的根中分离出10个次要皂苷（momordins Ia-Ie和IIa-IIe）沿着已知的主要皂苷（momordins I和II）。它们的结构是建立在化学和光谱分析的基础上。两种新皂苷的结构指定为3 β- {（[O-β- D-吡喃木糖基-（1 → D）2）-O-β- D-吡喃木糖基-（1 → D）3）]-O-β-苦瓜素Id和苦瓜素Id-28-β-D-吡喃葡萄糖醛酸基）氧基}-齐墩果-12-烯-28-酸苦瓜素D-吡喃葡萄糖酯IId.证实了存在于根中的真正皂苷不是单锁链苷而是双锁链苷，尽管前者是干根中的主要成分。
Ten minor saponins, momordins Ia-Ie and IIa-IIe, were isolated from the root of Momordica cochinchinensis, along with the known major saponins, momordins I and II. Their structures were established on the basis of chemical and spectroscopic analysis. The structures of the two new saponins were assigned as 3.beta.-{([O-.beta.-D-xylopyranosyl-(1 .fwdarw. 2)-O-.beta.-D-xylopyranosyl-(1 .fwdarw. 3)]-O-.beta.-D-glucopyranuronosyl)oxyl}-olean-12-ene-28-oic acid for momordin Id and momordin Id-28-.beta.-D-glucopyranosyl ester for momordin IId. It was confirmed that the genuine saponin present in the root was not the monodesmoside but the bisdesmoside, though the former is the major component in the dry root.
