概要

Soybean seeds were collected from 5 sites in Japan (20 cultivars, 31 samples), and the quantities of isoflavone, thiamine (vitamin B1), riboflavin (vitamin B2) and tocopherol (vitamin E) were determined. Of the analyzed elements, isoflavone and a-tocopherol equivalent tended to change greatly among the sample seeds. Total isoflavone content ranged from 131.6 to 568.7 mg/100 g DW in the whole samples, and the mean value was 302.9 mg/100 g DW. The coefficient of variation was 40.7%. For each site, total isoflavone content tended to change more than other elements, so that isoflavone appears to be easily influenced by the growing conditions of cultivars. α-tocopherol equivalent ranged from 3.4 to 13.3 mg/100 g DW, with a mean value 5.6 mg/100 g DW, and coefficient of variation of 40.5%. In soybean seeds, changes in α- and β-tocopherol were large, and the nutritional value of soybeans as a source of vitamin E was greatly influenced by changes in a-tocopherol content. The coefficient of variation for thiamine and riboflavin were 13.0 and 10.3%, respectively, and their variation was smaller than isoflavone or α-tocopherol equivalent. Samples of soybean cultivar Fukuyutaka were collec
