摘要
目的:建立薄荷麝香草酚搽剂中薄荷脑和麝香草酚的含量测定方法。方法:旋光法测定薄荷脑的含量,紫外分光光度法测定麝香草酚的含量。结果:薄荷脑在1.6~5.6mg/ml范围内浓度和吸收度具有良好的线性关系(r=0.9991),平均回收率为100.7%,RSD为0.7(n=9);麝香草酚在8.1~32.5μg/ml范围内浓度和吸收度具有良好的线性关系(r=0.9994),平均回收率为100.4%,RSD为1.6(n=9);结论:该法准确、可靠、快速,可用于薄荷麝香草酚搽剂的质量控制。
Objective:To stablished the method for determination of menthol and thymol in the Menthol and Thymol Liniment. Methods:Optical Rotation was used to determine the content of menthol.Ultravoilet spectrophotometry was used to determine the content of thymol.Results:The test of menthol was linear within the range of 1.6~5.6mg/ml(r=0.9991) .The average recovery was 100.7% with RSD of 0.7%(n=9) . The test of thymol was linear within the range of 8.1~32.5μg/ml(r=0.9994) .The average recovery was 100.4% with RSD of 1.6%(n=9) .Conclusions:The method is accurate,stable,rapid and the method canbe used for quality control of Menthol and Thymol Liniment.
