  3-Furanmethanol β-D-glucopyranoside (1) and (+)-catechin 7-O-β-D-glucopyranoside (3) were isolated from azuki beans, the seeds of Vigna angularis (WILLD.) OHWI et OHASHI (Leguminosae) and their structures were substantiated. The saponin mixture designated as total azukisaponin was also isolated from azuki beans. By means of enzymatic hydrolysis, acidic hydrolysis, and photochemical degradation, four genuine sapogenols, which included three known sapogenols, sophoradiol (7), soyasapogenol B (8), gypsogenic acid (9), and a new sapogenol named azukisapogenol (10), were isolated from total azukisaponin and the structure of 10 was elucidated. As one of the artifact sapogenols which were liberated by acidic hydrolysis of total azukisaponin, a new sapogenol named anhydrosophoradiol (5) was isolated and its structure was elucidated.

  从赤豆（Vigna angularis (Willd.) Ohwi et Ohashi 豆科）种子中分离得到3-呋喃甲醇β-D-吡喃葡糖苷（1）和（+）-儿茶素7-O-β-D-吡喃葡糖苷（3），并确定了它们的结构。从赤豆中还分离得到了总赤豆皂苷混合物。通过酶解、酸解和光化学降解，从总赤豆皂苷中分离出了4种真正的皂苷元，其中包括3种已知的皂苷元：染料木苷元（7）、大豆苷元B（8）、皂土酸（9）和一个新的皂苷元，命名为赤豆皂苷元（10），并阐明了其结构。作为总赤豆皂苷酸解释放的假皂苷元之一，分离得到了一个新的皂苷元，命名为无水染料木苷元（5），并阐明了其结构。
