大豆及其制品具有降血脂、抗氧化、抗癌、抗动脉粥样硬化等生理作用,主要应归功于大豆异黄酮。大豆经加工或微生物发酵经人体摄入后,在肠道细菌葡萄糖苷酶的作用下,异黄酮的糖苷配基脱离,释放出有生物活性的三羟异黄酮或称染料木黄酮(genistein,G)、二羟异黄酮或称大豆苷原(daidzein,D)和6-甲基大 Soybeans and their products with lipid-lowering, anti-oxidation, anti-cancer, anti-atherosclerotic and other physiological effects, mainly due to soy isoflavones. Soybean by processing or microbial fermentation by the body after ingestion, in the intestinal bacteria glucosidase under the action of isoflavone aglycone detached, release of bioactive genistein genistein (G ), Genistein or daidzein (D) and 6-methylglutaryl
