RESUMO
OBJECTIVE:To establish a method for the content determination of hordenine in Zang medicine Herba Aconiti. METHODS:HPLC was performed on the column of Gemini-NX C18 with mobile phase of acetonitrile-0.25 mol/l Ammonium ace-tate solution(ammonia water to adjust the pH to 9.5,gradient elution,at flow rate of 1 ml/min,the detection wavelength was 230 nm,the column temperature was 30 ℃,and the injection volume was 20 μl.RESULTS:The linear range of hordenine was 3.276-819μg/ml(r=0.999 5);RSDs of precision,stability and reproducibility tests were lower than 2.0%;recovery was 96.21%-104.04%(RSD=1.23%,n=9). CONCLUSIONS:The method is simple,stable and reproducible,and can be used for the content determi-nation of hordenine in Zang medicine Herba Aconiti.
