Abstract:
Objective To set up the quality standard of Renqing Mangjue capsules. Methods TLC was used for qualitative identification of Crocus sativus, Zingiberaceae, Syringa oblata, Radix Aucklandiae and Borneolum. The content of Brucine and Strychnine were determined by HPLC, which conducted with CAPCELL PAK MG C18 column (4.6 mm×250 mm, 5μm). The mobile phase consisted of methanol∶0.01 moL/L potassium dihydrogen phosphate (with 10%phosphoric acid to adjust the pH 2.5)=25∶75 and the flow rate was 1.0 mL/min. The detection wavelength was set at 254 nm and 260 nm. The column temperature maintained at 30 ℃. Results TLC could detect qualitatively Crocus sativus, Zingiberaceae, Syringa oblata, Radix Aucklandiae and Borneolum. The spots were clear and the negative controls had no interference. HPLC determined that Brucine presented a good linear relationship in the range of 0.012 1-0.072 8 μg (r=0.999 1). The average recovery was 97.27%, RSD was 1.20%. Strychnine presented a good linear relationship in the range of 0.045 4-0.272 4 μg (r=0.999 8). The average recovery was 98.69%, RSD was 1.17%. Conclusion The method is simple in operation. The results are accurate, reliable and good in reproducibility. The method can effectively control the quality of Renqing Mangjue capsules.
