对广州相思子 (Abrus cantoniensis) 全草植物相思子 (Abrus cantoniensis) 23 种皂苷中的 6 种皂苷 So1 (1)、So2 (2)、D2 (3)、D3 (4)、F (5) 和 SB (6) 进行了化学结构研究。它们被阐明为 3-O-α-L-吡喃鼠李糖基-(1 --> 2)-[O-β-D-吡喃葡萄糖基-(1-->3)]-β-D-吡喃半乳糖基-(1 --> 2)-β-D-吡喃葡萄糖醛酸基[序列：见文本]（指定为 β-abritetraosyl）槐二醇 (1)， 3-O-β-abritetraosyl abrisapogenol D 22-O-β-D-木吡喃糖苷 (2)、3-O-β-abritetraosyl abrisapogenol D (3)、O-β-abritetraosyl abrisapogenol D 22-O-β-D-吡喃葡萄糖苷 (4)、3-O-β-abritetraosyl abrisapogenol F (5) 和分别为 3-O-β-abritetraosyl soyasapogenol B (6)。
The chemical structures of abrisaponins So1 (1), So2 (2), D2 (3), D3 (4), F (5) and SB (6), six of twenty-three saponins from Abri Herba, the whole plants of Abrus cantoniensis (Leguminosae), were investigated. They were elucidated to be 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-[O-beta-D-glucopyranosyl-(1-->3)]-beta-D-galactopyranosyl-(1 --> 2)-beta-D-glucuronopyranosyl [sequence: see text] (designated as beta-abritetraosyl) sophoradiol (1), 3-O-beta-abritetraosyl sophoradiol 22-O-beta-D-xylopyranoside (2), 3-O-beta-abritetraosyl abrisapogenol D (3), O-beta-abritetraosyl abrisapogenol D 22-O-beta-D-glucopyranoside (4), 3-O-beta-abritetraosyl abrisapogenol F (5) and 3-O-beta-abritetraosyl soyasapogenol B (6), respectively.
