摘要
目的:采用 HPLC 法测定丹皮酚软膏(霜)中丹皮酚的含量。方法:色谱柱为 Hypersil C_(18)柱(150 mm×4.6 mm,5 μm);流动相:甲醇-水(50:50);流速1.0 mL·min^(-1);检测波长:274 nm。结果:丹皮酚进样量在0.05~0.54 μg范围内呈良好线性关系(r=0.9998),平均回收率(n=6)为98.7%,RSD 为2.0%。结论:本法准确,重现性好。
Objective:Use an HPLC method to determine the contents of paeonol in the compound paeonol cream. Method : Hypersil C18 column (150 mm ×4. 6 mm, 5μm) was used;The mobile phase consisted of methanol -water (50: 50) ,at a flow rate of 1.0 mL·min^-1 ;The detection wavelength was 274 nm. Results:Paeonol has a good linear relation in the range of 0. 05 -0. 54μg( r = 0. 9998 ), the average recovery( n = 6)was 98.7% (RSD = 2. 0% ). Conclusion:The method is accurate and reproducible.
