Analysis of Soybean Isoflavones Content and Its Components in Different Soybeans

This experimentation use the edible ethanol to extract,and use the high performance liquid chromatography to analyse the content of soybean isoflavones of 8 soybean cultivars.Five kind of isoflavone components including Daidzin,Genistin,Daidzein,Glycitin,and Genistein were detected and content of each component was determined.Results showed that content of soybean isoflavones and its components varied greatly with cultivars.Soybeans with yellow seed coat had higher isoflavones content and Jinong17 had the highest content of 6.6‰.
