| Abstract: | 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. |
