皂角皂苷C(GS-C)是皂角果皮中的一种主要三萜皂苷。(豆科)，由棘球藻酸、8个糖基和2个单萜基((+)2，6-二甲基和(+)2-hydroxymethyl-6-methyl-6-(S)hydroxy-2-trans-2，7-octadienoyl基团)组成。GS-C的甲基化分析、气相色谱和质谱分析表明，单萜基连接在C-28寡糖部分的2和3位L-鼠李糖末端。
The chemical structure of gleditsia saponin C (GS-C), a major triterpenoid saponin of the fruit capsule of G. japonica Miq. (Leguminosae), comprised echinocystic acid, 8 sugar units and 2 monoterpenyl groups ((+)2,6-dimethyl- and (+) 2-hydroxymethyl-6-methyl-6-(S)hydroxy-2-trans-2,7-octadienoyl groups). Methylation analysis of GS-C followed by determination with GLC and mass spectrometry showed that the monoterpenyl moieties attach to the 2 and 3 positions of terminal L-rhamnose of the C-28 oligoside portion.
