Abstract:
Objective To establish an HPLC method to determine the contents of dauricine in Menispermi Rhizoma from different producing areas. Methods C18 was set as chromatographic column filler, with acetonitrile-water-triethylamine (45:55:0.1) as the mobile phase, 284 nm as the ultraviolet wavelength detection, 1 mL/min as the flow rate, 30 ℃ as the column temperature. HPLC chromatograms of eight different batches of Menispermi Rhizoma were established. Results HPLC testing conditions of Menispermi Rhizoma was established. Within 20-100 μg/mL, there was a good linear relationship between the injection volume of the reference substance and the peak area (r=0.9995). The average recovery of dauricine was 100.30%, RSD=1.000%. The contents of dauricine in Menispermi Rhizoma from different producing areas were different. Conclusion The HPLC method is with sensitivity, accuracy, precision, good reproducibility and simple operation, which can be used as detection method to determine the content of dauricine in Menispermi Rhizoma.
