从苦瓜根中提取。分离得到3个皂苷，分别命名为苦瓜素I、苦瓜素II和苦瓜素III。其结构经化学和波谱确证为齐墩果酸3-O-α-L-阿拉伯吡喃葡萄糖苷(1-→3)-β-D-葡萄糖醛酸吡喃糖苷(苦瓜素I)，苦瓜素I的28-O-β-D-吡喃葡萄糖苷(苦瓜素II)和3-β-羟基-11α，12-α-环氧-油-28，13-内酯3-O-α-L-阿拉伯吡喃葡萄糖苷(1→3)-β-D-葡萄糖醛酸吡喃糖苷(苦瓜素III)。苦瓜素II被证明与从大花灯盏花和中国灯盏花块茎中分离得到的半夏草苷MA1相同。
From the root of Momordica cochinchinensis SPRENG. (Cucurbitaceae), three saponins named momordins I, II and III have been isolated. Their structures were determined on the basis of chemical and spectral evidence as oleanolic acid 3-O-α-L-arabinopyranosyl (1→3)-β-D-glucuronopyranoside (momordin I), 28-O-β-D-glucopyranoside of momordin I (momordin II) and 3β-hydroxy-11α, 12α-epoxy-olean-28, 13-olide 3-O-α-L-arabinopyranosyl (1→3)-β-D-glucuronopyranoside (momordin III). Momordin II was proved to be identical with hemsloside Ma1 isolated from the tubers of Hemsleya macrosperma and H. chinensis.
