soyasapogenol a/ダイズ

An efficient analytical method utilizing high-performance liquid chromatography (HPLC)/evaporative light scattering detector (ELSD) was developed to isolate and quantify the two major soyasaponin aglycones or precursors in soybeans, triterpene soyasapogenol A and B. Soaking of seeds in water up to

The growth inhibition and the induction of apoptosis brought about by soyasaponins extracted from soy flour ( Glycine max (L.)) and concentrated for soyasapogenols A and B formed by hydrolysis were tested for cytoactivity in the human hepatocellular carcinoma cell line Hep-G2. Concentrated

This study investigated the functional compounds, including isoflavones, phenolics, soyasapogenols, and tocopherols, that were detected in 204 soybean [ Glycine max (L.) Merrill] germplasms. The soybean samples were divided into three groups according to origin: America, China, and Korea. The

Saponins are secondary metabolites that are widely distributed in plants. There are two major saponin precursors in soybean: soyasapogenol A, contributing to the undesirable taste, and soyasapogenol B, some of which have health benefits. It is important to control the ratio and content of the two

Triterpenoid saponins are one of the most highly accumulated groups of functional components in soybean (Glycine max) and the oxidative reactions during their biosynthesis are required for their aglycone diversity. Natural mutants of soyasaponins in wild soybean (Glycine soja) are valuable resources

Triterpene saponins are a diverse group of biologically functional products in plants. Saponins usually are glycosylated, which gives rise to a wide diversity of structures and functions. In the group A saponins of soybean (Glycine max), differences in the terminal sugar species located on the C-22
