Introduction

In collaboration with the National Agriculture and Food Research Organization, Shimadzu Corporation has been developing a simple, quick and accurate method of analyzing functional components in agricultural and food products. In this report, we introduce the method for analyzing isoflavones in soybeans and report the results of confirming the isoflavone content in one soybean variety. Soy isoflavones are components that are conteined in soybeans, especially soybean germ. Soy isoflavones usually have a sugar-bound structure. Aglycone is known to have an estrogen-like effect because its molecular structure resembles that of human estrogen (female hormone). Therefore, the maximum daily intake of soy isoflavone recommended is 75 mg/day in Japan. In this report, an analysis method of soy isoflavones was developed.
