摘  要:目的:建立同时测定丹知青娥片中补骨脂素、异补骨脂素、补骨脂苷、异补骨脂苷含量的方法。方法:采用高效液相色谱法。色谱柱为EclipseXDB-C18流动相分别为甲醇-水(51:49,V/V(等度洗脱分析补骨脂素和异补骨脂素)、乙腈-0.1%甲酸水溶液(12:88,V/V)(等度洗脱分析补骨脂苷和异补骨脂苷),流速为1.0ml/min,检测波长为246nm,柱温为30℃,进样量为10μl。结果:补骨脂素、异补骨脂素、补骨脂苷和异补骨脂苷的检测质量浓度线性范围分别为3.138~200.8、3.175-203.2、3.18l~101.8、3.169~101.4ug/ml(r均为0.9999);定量限分别为0.6275、0.6350、3.181O、3.1690ng,检测限分别为0.2510、0.2540、1.2730、1.2680ng;精密度、稳定性、重复性试验的RSD〈2%;加样回收率分别为95.68%~102.80%(RSD=2.4%,n=6)、95.91%~102.10%(RSD=2.3%,n=6)、98.64%~99.13%(RSD=0.23%,n=6)、100.20%~101.70%(RSD=0.69%,n=6)。结论:该方法操作简便、结果准确.可用干同时测定丹知青娥片中补骨脂素、异补骨脂素、补骨脂菩、异补骨脂苷的会量。OBJECTIVE : To establish a method for the contents determination of psoralen, isopsoralen, psoralenoside and isop- soralenoside in Danzhi qing' e tablet. METHODS : HPLC performed on the column of Eclipse XDB-C18 with mobile phase of metha- nol-water (51:49, V/V) (isocratic elution, for psoralen and isopsoralen) and acetonitrile-0.1% formic acid (12:88, V/V) (isocratic elution, for psoralenoside and isopsoralenoside) at a flow rate of 1.0 ml/min, the detection wavelength was 246 nm, column tem- perature was 30℃, and injection volume was 10 pl. RESULTS: The linear range was 3.138-200.8 pg/ml for psoralen (r=0.999 9), 3.175-203.2μg/ml for isopsoralen(r=0.999 9),3.181-101.8μg/ml for psoralenoside (r=0.999 9) and 3.169-101.4 pg/ml for isopso- ralenoside (r=0.999 9) ; RSDs of precision, stability and reproducibility tests were lower than 2% ; limits of quantitation were 0.627 5 ng, 0.635 0 ng, 3.181 0 ng and 3.169 0 ng,the limits of detection were 0.251 0 ng, 0.254 0 ng, 1.273 0 ng and 1.268 0 ng; recoveries were 95.68% -102.80% (RSD=2.4% , n=6) , 95.91% -102.10% (RSD=2.3% , n=6) , 98.64% -99.13% (RSD= 0.23%, n=6) and 100.20%-101.70% (RSD=0.69%, n=6), respectively. CONCLUSIONS: The method is simple and accurate, and can be used for the simultaneous determination of psoralen, isopsoralen, psoralenoside and isopsoralenoside in Danzhi qing'e tablet.
