Abstract:
OBJECTIVE:To establish a method for the content determination of sinalbin in Sinapis alba decoction piece. METHODS:HPLC was performed on the column of Sepax HP-C18 with mobile phase of 50% acetonitrile-water solution(contain-ing 5 mmol/L tetraoctyl ammonium bromide)at a flow rate of 1.0 ml/min,detection wavelength was 227 nm,column temperature was 30 ℃,and the injection volume was 10 μl. RESULTS:The linear range of sinalbin was 0.010 1-0.202 4 mg/ml(r=0.999 7);RSDs of precision,stability and reproducibility tests were lower than 2%,recovery was 98.51%-104.62%(RSD=1.90%,n=9). CONCLUSIONS:The method is simple,accurate and reliable,and can be used for determination of sinalbin in Sinapis alba decoc-tion piece.
