OBJECTIVE:To establish a method for the simultaneous determination of curdione, germacrone and furanodiene of zedoray turmeric oil in Ruxiankang injection. METHODS:HPLC was performed on the column of Zorbax SB-C18 with mobile phase of acetonitrile-water (gradient elution) at a flow rate of 1.0 ml/min, detection wavelength was 216 nm, column temperature was 30 ℃, and the injection volume was 10 μl. RESULTS: The linear range was 60-480 μg/ml for curdione(r=0.999 0),40-320 μg/ml for germacrone (r=0.999 0) and 40-320 μg/ml(r=0.999 0); RSDs of precision, stability and reproducibility tests were lower than 2.0%; recoveries were 95.21%-99.89%(RSD=1.6%,n=6),102.33%-104.89%(RSD=1.0%,n=6) and 97.38%-99.06% (RSD=0.7%,n=6), respectively. CONCLUSIONS: The method is simple and accurate, and can be used for simultaneous contents determination of curdione, germacrone and furanodiene of zedoray turmeric oil in Ruxiankang injection.
