Abstract:Objective: To establish the determination method for shikonin in WuZi cataplasm. Methods: High performance liquid chromatography (HPLC), chromatographic condition, chromatographic column: agilent C18 column (4.6 min×250 mm, 5 μm), mobile phase: methanol-0.1% phosphate buffer solution (80:20), detection wavelength: 516nm, column temperature:25℃, flow rate was 10mL/min. Results: Sample size was in the range between 8.2 and 41.0 μg/mL, linear relationship was better (r=0.999 9), average recovery rate was 101.30% (RSD was 1.55%, n=9). Conclusion: HPLC determining the contents of shikonin in IguZi cataplasm is accurate and repro- ducible, which could be applied to quality control ofWuZi cataolasm.
Keywords:WuZi cataplasm  high performance liquid chromatography  shikonin  content determination
