  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）。

  Indirect anodic oxidation of soyasapogenol B (3β, 22β, 24-trihydroxyolean-12-ene) was carried out using KI as a mediator in t-BuOH-H2O solution, so that the 3-ketone derivative was obtained as the only oxidation product in a favorable yield. As a result of application to various polyhydroxylated triterpenes, selective electrochemical oxidation was shown to occur in the C-3 hydroxyl group of the polyhydroxyl triterpenes with the C-24 hydroxyl group. The reaction pathway is discussed.

  以 KI 为介质，在 t-BuOH-H2O 溶液中对大豆苷元 B（3β, 22β, 24-三羟基油菜素-12-烯）进行了间接阳极氧化，从而获得了 3-酮衍生物作为唯一的氧化产物，且产率较高。对各种多羟基三萜的应用结果表明，多羟基三萜的 C-3 羟基与 C-24 羟基发生了选择性电化学氧化反应。对反应途径进行了讨论。

  Two new bisdesmosides of soyasapogenol A (1), named soyasaponin A1 and soyasaponin A2 (7), were isolated from soybean, the seeds of Glycine max MERRILL, together with the known soyasaponins I (4), II (5), and III (6). By employing a photochemical degradation method, which is a selective cleavage method for the glucuronide linkage in oligoglycosides, and on the bases of spectral analyses and chemical reactions, the structure of soyasaponin A2 was elucidated as 3-O-[β-D-galactopyranosyl (1→2)-β-D-glucuronopyranosyl]-22-O-[β-D-glucopyranosyl (1→3)-α-L-arabinopyranosyl] soyasapogenol A (7).
