摘要
目的 测定保心宁软胶囊中丹参素含量。方法 用高效液相色谱(HPLC)法测定保心宁软胶囊中丹参素含量,0DS-C18(150mm×6mm,5μm)色谱柱,流动相为0.5%冰醋酸-甲醇(87:15),检测波长为280。结果 线性范围为8-60μg/ml(r=0.9997),回归方程为Y=0.2593x+0.4134,平均回收率为99.83%,RSD为1.48%。结论 该法简便,快速,准确,重现性好。
Objective To establish the method of determining Cryptotanshinone of soft capsule BaoXinNing. Methods HPLC was carried out for determining Cryptotanshinone with column : ODS-C18 ( 150 Mm×6 mm,5μm), mobile phase :0.5 % glacial acetic acid and methanol (87: 15), wavelength :280 nm. Results The linearity of Cryptotanshinone was in range of 8 N 60μg/ml( r = 0. 999 7), the average recovery rate is 99.61%, and RSD is 1.13%. Conclusion The method is simple, correct and with good reproducibility.
