ABSTRACT
Objective To establish a method for quality control of Arnebia euchroma inZizhu Ointment.Methods The TLC was used to make qualitative identification to Arnebia euchroma in Zizhu Ointment. The content of shikonin was targeted as the evaluation index and the method of orthogonal design was used to optimize the extraction of shikonin. UV-visible spectrophotometry was used for the determination of shikonin.Results Main spots of TLC were clear, and negative control had no interference. The optimum extraction of shikonin was extracted for three times, 30 min for each time, NaOH volume fraction of 1%, NaOH amount of 50 mL. The absorbance of shikonin showed a good linear relationship in the range of 0.010 2-0.035 7 mg (r2=0.999 7), and the average recovery was 103.27%, RSD=4.17%.Conclusion This method was simple and feasible, and can be used for the quality control and the evaluation ofZizhu Ointment.
