摘要
目的：用HPLC法测定鼻康宝胶囊中黄芩苷的含量。方法：采用Kromasil C18柱，以甲醇-水-磷酸（40：60：0．2）为流动相，检测波长280nm。结果：黄芩苷在5．2～83．2μg/mL范围内峰面积与浓度呈良好性线形关系，r=0．9998，平均回收率为97．8％。结论：该方法专属性强、简便、精密度好、结果准确可靠。
Objective： To establish a method for determination of baiealin in Bikangbao capsule by HPLC. Methods： HPLC was performed on Kromasil C18 column with methanol-water- phosphonic acid （40： 60： 0.2） as mobile phase. The UV detection wavelength was 280 nm. Results： The linear range of baicalin was sample size 5.2 - 83.2 μg/mL （ r = 0. 9998 ） , the average recovery was 97.8%. Conclusions ： The method was simple, accurate and fast, and could be used for the determination of baicalin in Bikangbao capsule.
