Objective To establish a method for determination of Imperatorin and Isoimperatorin in Tianmatoutongpian by HPLC .Method The two substances were determined with HPLC .An waters Symmetry C18 column (4.6 ×250mm,5μm)was gradient elu-ted with acetontrile -water at a flow rate of 1.0 ml per min at 250nm,and column temperature was at 25℃ .Result Imperatorin had a good linearity relationship between 1.424μg/ml-71.2μg/ml and the average recovery was 102.9% (RSD 1.45%),Isoimperatorin had a good linearity relationship between 1.337μg/ml -66.85μg/ml and the average recovery was 102.5% (RSD 1.85%).Conclu-sion The method can be used to determined of Imperatorin and Isoimperatorin in Tianmatoutongpian.
