Abstract
Objective：To analyse and compare the effect of sodium metavanadate on the synthesis of isoflavones including daidzein and genistein in soybean sprouts.Method：Soybean seeds were germinated in sodium metavanadate solutions（NaVO3） with different concentrations（0,200,400,600,800,1000,1200,1400,1600mg/L NaVO3） for 6 days at 28℃.The V-enriched soybean sprouts were harvested on the sixth day,the isoflavones including daidzein and genistein were extracted with 95% alcohol,and the contents of daidzein and genistein were determined with HPLC.Result：Soybean seeds germinated in 200～600mg/L NaVO3 solutions for 6 days at 28℃ showed ahigher content of isoflavones including daidzein and genistein than those obtained in NaVO3 solutions with other concentration in the same germination donditions.Conclusion：The application of NaVO3 solutions at a concentration of 200～600mg/L and germination for 6 days at 28℃ may be suggested for the production of the V-enriched chickpea sprouts,when comprehensively considering the contents of daidzein and genistein in soybean sprout together with its growth conditions.关键词
