Abstract: | [Objective] The aim was to determine the content of the isoflavones in the leaves and the stems of Manglietia hainanensis.[Methods] Genistein was viewed as reference substance,the ultraviolet spectrophotometric method was used to determine the content of the isoflavones in the leaves and branches of Manglietia hainanensis.[Results]The calibration curve was linear in the range of 0.000 5-0.004 5 μg/ml,and the regression equation was C=0.003 9A,R=0.999 9,the content was 0.240 % and 0.078 %.[Conclusion] The spectrophotometry was suitable for the determination of isoflavones from the leaves and branches of Manglietia hainanensis.This method operated conveniently,the result was stable and has good repeatability. |
