Saponins are a diverse group of plant secondary metabolites with a wide array of activities, as well as a significant role in nutrition and health. Saponins occur as multi-component mixtures of compounds with very similar polarities. Soysaponins are a special group of saponins. These represent the main source of saponins in Glycine max (soybeans, Fabaceae). In a study of the chemical profiling of plants, to investigate the possible misidentification and authentication of dietary supplements, the hydro-alcoholic extract of G. max was investigated. Three new saponins, designated as soysaponins M1 (1), M2 (2) and M3 (3) along with seven known soysaponins (4-10) were isolated by normal and reverse phase liquid chromatography. All compounds were characterized by spectroscopic techniques including 2D NMR spectroscopy.
皂苷是一类具有广泛活性的植物次生代谢产物，在营养和健康方面具有重要作用。皂苷是以化合物的多组分混合物形式存在，极性非常相似。大豆皂苷是皂苷的特殊类别。这些是 Glycine max（大豆，豆科）中皂苷的主要来源。在对植物化学特征的研究中，为了研究膳食补充剂的可能错误识别和鉴定，对 G. max 的水醇提取物进行了研究。通过正相和反相液相色谱法分离出三种新的皂苷，命名为大豆皂苷 M1（1）、M2（2）和 M3（3），以及七种已知的大豆皂苷（4-10）。所有化合物均通过包括 2D NMR 光谱在内的光谱技术进行了表征。
