摘要
目的建立左归丸中熊果酸的含量测定方法。方法双波长薄层扫描法，以环己烷-氯仿-乙酸乙酯-冰醋酸（20：5：8：0．5）为展开剂，测定波长543nm，参比波长700nm。结果平均回收率96．33％（RSD=1.03％）。标准曲线r=0．999，线性范围0．30445—3．0445μg。结论该法准确、重复性好，可作为左归丸的质控方法。
Aim To establish a TLCS method for determination of Ursolic acid in Zuogui pills. Method Dual - wavelength scanning was performed. The developing solvent was cyclohexane-chloroform-ethyl acetate-acetic acid glacial （20： 5： 8： 0.5）, The detection wavelength was 543nm and 700nm. Results The average recovery was 96.33% , and RSD was 1.03%. For Ursolic acid the linear range was between 0.30445 and 3.0445 μg （ r = 0.99 9）. Conclusion The method is simple and accurate. It can be used for the quality control of Zuogui pills.
