【摘要】 测定克糖片剂中槲皮素的质量比.采用高效液相色谱法,Hypersil C18柱,流动相为甲醇-0.3%磷酸(60∶40,V∶V),流速为1.0 mL/min,柱温为室温,柱长为250 mm,检测波长为360 nm.槲皮素的线性范围为0.2~1.0μg(r=0.999 9),槲皮素的平均加样回收率为99.57%(RSD为0.51%).最终计算得出平均含槲皮素0.052 7 mg/片,RSD为0.48%.本方法可简便快捷的测得克糖片剂中槲皮素的质量比.更多还原

【Abstract】 To determine the content of quercetin in Ketang tablet.High performance liquid chromatography is established on a Hypersil C18 column with mobile phase consist of methanol-0.3% phos-phoric acid(60∶40,V∶V) and flow rate of 1.0 mL / min at a common temperature.The column length is 250 mm,and the detection wavelength is 360 nm.The linear range of quercetin is 0.2 ~ 1.0 μg(r = 0.999 9).The average recovery is 99.57%(RSD= 0.51%).The average content of quercetin is 0.0527 mg / tablet(RSD =0.48%).The method is simple and efficient to measure the content of quercetin.更多还原
