摘  要:目的:建立用高效液相色谱法同时测定中药瓦松中槲皮素和山萘素的方法。方法:采用Thermo C_18(4.6mm×250mm,5μm)色谱柱,流动相甲醇-醋酸盐缓冲液(53:47),体积流量1.0mL·min-1,柱温30℃,检测波长360nm,进样体积为20μL。结果:槲皮素和山萘素分别在3.92~11.76mg·L-1(r=0.9998),10.03~30.09mg·L-1(r=0.9999)线性关系良好。平均回收率分别为99.85%,100.07%;RSD(n=9)分别为0.78%,1.05%。结论:该方法简便快速,结果准确,重复性好,可用于瓦松药材的质量控制。Objective: To establish an HPLC method for determination quercetin, kaempferol in Herba Orostachgdis Fimbriati. Method: The separation was performed on Thermo C18 (4.6 mm × 250 mm, 5 μm) column. The mobile phase consisted of methanol-acetate buffer solution (53: 47) with the flow rate of 1.0 mL · min-1, the column temperature was 30 ℃ , and the detection wavelength was 360 nm, sample size was 20 μL. Result: The quercetin, kaempferol were linear in the ranges of 3.92-11.76 mg ·L-1 (r = O. 999 8) , 10.03- 30.09 mg · L-1 ( r = O. 999 9 ) , respectively. The average recoveries were 99.85% , 100.07% ( n = 9 ) , respectively. RSDs were 0.78%, 1.05%, respectively. Conclusion: The method is simple, accurate and reproducible, and can be used for the quality control of Herba Orostaehgdis Fimbriati.
