  Five bioactive triterpene-oligoglycosides, named soyasaponins I, II, III, A1 (3), and A2 (2), were isolated from soybean, the seeds of Glycine max MERRILL (Leguminosae). By employing a photochemical degradation method and a lead tetraacetate degradation method, which are two of four selective cleavage methods available for the glucuronide linkage in oligoglycosides, the structure of soyasaponin A1 was elucidated to be 3-O [β-D-glucopyranosyl (1→2)-β-D-galactopyranosyl (1→2)-β-D-glucuronopyranosyl-22-O-[β-D-glucopyranosyl (1→3)-α-L-arabinopyranosyl]-soyasapogenol A (3).

  从豆科植物大豆（Glycine max Merrill）的种子中分离出五种具有生物活性的三萜类低聚糖苷，分别命名为大豆皂苷I、II、III、A1（3）和A2（2）。通过采用两种选择性裂解方法，即光化学降解法和四乙酸铅降解法（这是四种可用于低聚糖苷中葡萄糖醛酸连接的选择性裂解方法中的两种），阐明了大豆皂苷A1的结构为：3-O[β-D-葡萄吡喃糖基（1→2）-β-D-半乳吡喃糖基（1→2）-β-D-葡萄糖醛吡喃糖基]-22-O[β-D-葡萄吡喃糖基（1→3）-α-L-阿拉伯吡喃糖基]-大豆皂苷元A（3）。

  Two monoterpene glycosides 1 and 2 were isolated from the fruits of Gymnocladus chinensis BAILLON (Leguminosae). On the basis of chemical and physicochemical evidence, these glycosides were characterized as (6S)-2-trans-6-α-L-arabinopyranosyloxy-2, 6-dimethyl-2, 7-octadienoic acid and (6S)-2-trans-2, 6-dimethyl-6-[3-O-(β-D-glucopyranosyl)-4-O-(2-methylbutyroyl)-α-L-arabino-pyranosyloxy]-2, 7-octadienoic acid.
