RESUMEN
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.
RESUMEN
OBJECTIVE:To observe the clinical curative effect of Danshen and Chuanxiongqin injetion for frequent attacks of transient cerebral ischemia. METHODS: A total of 78 patients with frequent attacks of transient cerebral ischemia were enrolled:40(treatment group) were assigned to receive Danshen and Chuanxiongqin injection 10 mL with 0.9% physionlogical saline 200 mL iv gtt q.d, 38 (control group) to receive Xuesaitong injection 10 mL with 0.9% physiological saline 200 mL iv gtt q.d for 14 days(for both group).RESULTS: There were significant differences between the treatment group and the control group in effective rate (95.00% vs.57.89% respectively) (P
