摘 要:目的建立测定金铃子滴丸中延胡索乙素含量的高效液相色谱法。方法采用HPLC法测定延胡索乙素含量,色谱柱为依利特C18(4.6mm×200mm,5μm);流动相为甲醇∶0.1%磷酸溶液(三乙胺调pH值至6.0)(55∶45);检测波长为280nm,流速为1.0mL·min-1,柱温为30℃,进样量10μL。结果延胡索乙素在0.01~0.20mg.mL-1范围内质量浓度与峰面积呈良好的线性关系,相关系数r=0.9999(n=7);平均回收率为100.25%,RSD为1.71%(n=6);重复性实验的相对标准偏差RSD为1.87%(n=6)。结论该测定方法重复性好、灵敏度高并且简便、准确,可作为金铃子滴丸中延胡索乙素含量的测定方法。Objective:To establish a method of HPLC for determining the content of tetrahydropulmatine in fructus toosendan drop pill.Methods:HPLC was adopted to determine the content of tetrahydropulmatine,with Elite C18 column(4.6 mm×200 mm,5 μm)and mobile phase,methanol:0.1% phosphoric acid(pH value of triethylamine:6.0)(55∶45),at 280 nm;flow rate,1.0 mL·min-1,at 30 ℃ of column temperature and 19 μL of sample input.Results:The good linear relation between quality concentration and peak area for tetrahydropulmatine presented in the range from 0.01 to 0.20 mg·mL-1,and the relation factor(r)= 0.999 9(n=7).The average recovery was 100.25% and RSD was 1.71%(n=6).RSD of repeatable experiment was 1.87%(n=6).Conclusion:The method is good in repeatability,high in sensitivity,sample and accurate in operation,which is suitable for the determination of the content of tetrahydropulmatine in fructus toosendan drop pill.
