title: Saponins from Glycine max Merrill (soybean).
abstract: 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.
