OBJECTIVE: To establish a method for simultaneous determination of luteolin and apigenin in Mongolian medicine Scabiosa atropurea. METHODS: HPLC was performed on the column of Diamond C18 with mobile phase of acetonitrile-0.4% phosphoric acid (34 ∶ 66,V/V) at a flow rate of 1.0 ml/min,the detection wavelength was 350 nm, column temperature was 30 ℃, and the injection volume was 10 μl. RESULTS: The linear range was 66-396 ng for luteolin (r=0.999 8) and 93-558 ng for apigenin(r=0.999 6); RSDs of precision, stability and reproducibility tests were lower than 2%; recoveries were 98.15%-101.79% (RSD=1.42%,n=6) and 98.66%-104.05%(RSD=1.81%,n=6),respectively. CONCLUSIONS: The method is simple with good precise, stability and reproducibility, and can be used for the simultaneous determination of luteolin and apigenin in Mongolian medicine S. atropurea.
