| Abstract: | The selenium content in Winged Bean was determined by spectrophotometry.The analytical result showed the selenium contents in the tuberous roots,stems,leaves,flowers,tender pods,seeds and the whole plant of winged bean were 1.58,4.17,6.08,9.42,7.00,5.83 and 5.08 μg/g respectively, in dry sample.The method is sensitive and precise with RSA of less 3% and the recovery of 97.0%.The study provided scientific basis for the development of winged bean,and had important guiding significance in both theory and practice. |
