摘要
目的建立HPLC法测定麝香止痛贴膏的药材浸膏中欧前胡素含量的方法。方法采用高效液相色谱法,COSMOSIL MS-Ⅱ柱(250mm×4.6mm,5um);流动相:甲醇-水(54:46);流速:1.0mL·min^-1;检测波长:300nm:柱温:40℃。结果欧前胡素在25.12~226.1ng范围内呈良好的线性关系,回收率为99.95%,RSD为1.84%。结论本方法简便、快速、准确,可用于测定麝香止痛贴膏药材浸膏中欧前胡素的含量。
Objective: To establish HPLC to determine the Imperation Content in Medicinal Materials of Muskiness Analgetic Plaster. Method: HPLC was adopted. COSMOSIL MS - Ⅱ eolum (250mm ×4.6mm, 5um) ; mobile phase: methanol -water (54 : 46) ; velocity: 1.0mL· min^-1; vetection wavelength: 300nm; column temperature: 40℃. Results: In the scope of 25.12 -226. lng the imperation content was in an excellent linear relationship, and the recovery was 99.95% , RSD was 1. 84%. Conclusions: This method is so simple, efficient and accurate that it can be used to determine the imperation content in medicinal materials of muskiness analgetie plaster.
