| Abstract: | High-performance liquid chromatography analysis is used to examine the distribution of isoflavones in different parts of soybean sprouts. Between the seed leaf and hypocotyl, the ratio of isoflavones differs depending on the aglycone type. Glycitein exists predominantly in the hypocotyl. Three compounds isolated from 4-day-old seed coats were identified as coumestrol and its glycosides. |
