Résumé

Objective To revise the qualitative and quantitative determination methods of Xuanxi Rongjin powder. Methods TLC was used to qualitatively identify Chuanxiong and Chuanshanlong. The content of cinnamaldehyde in the preparation was determined by HPLC with KR100-5C18 column (250 mm×4.6 mm, 5μm). The mobile phase was acetonitrile-water (35:65) and the detection wavelength was 290 nm. Results TLC can qualitatively identify Chuanxiong and Chuanshanlong. Cinnamaldehyde has a good linear relationship in the range of 0.0489~0.3260 µg/ml (r=1.00), The average recovery was 95.71% (RSD=1.78%). Conclusion The method has high sensitivity, good specificity, simple operation and good reproducibility.
