Title: UV Spectrometry Method to Determine Daidzein in Soybean Extract
Abstract:There was significant difference between the two daidzein values in the soybean extract determined by UV(at 248 nm)and HPLC(t test,t0.01).UV standard curve was corrected by mathematic method and HPLC ...There was significant difference between the two daidzein values in the soybean extract determined by UV(at 248 nm)and HPLC(t test,t0.01).UV standard curve was corrected by mathematic method and HPLC values as truth-values,a new relationship between concentration(y)and absorbency(x),y=0.706 1x+0.012 5,was established,with no significant difference between UV and HPLC,the recovery of 99.128 % and the relative standard deviation(RSD)of 5.387 % for daidzein detection.Read More
