高效液相色譜法%黃芩苷%清熱解毒片
고효액상색보법%황금감%청열해독편
HPLC%Baicalin%Qing re jie du Tablets
目的采用高效液相色谱法测定清热解毒片中黄芩苷的含量。方法用十八烷基硅烷键合硅胶作为填充剂,用甲醇-0.2%磷酸溶液(48院52)为流动相,流速1.0 ml·min-1,检测波长280nm。结果该试验的结果为清热解毒片中黄芩苷进样量在0.13~0.95μg范围中线性关系良好(该区间中r=0.9996),精密度试验RSD为1.11%,重复性试验RSD为1.16%,平均回收率为100.13%,RSD为1.30%(n=6)。结论本方法操作比较简便,精密度好,结果准确可靠,适用于清热解毒片中黄芩含量的测定。

Objective To determine Baicalin Content in Qing re jie du Tablets by HPLC. Methods HPLC analysis was carried out with Hypersil BDS C18 and Methy Alcohol-0.2%Phosphoric acid (48:52) as mobile phase,The flow rate was 1.0 ml·min-1,the detection wavelength was 280 nm. Results The calibration curve was linear in the range of 0.12~0.96 μg for Baicalin (r=0.9996), The average recovery was 100.13%(n=6).Conclusion The method is rapid, accurate , reliable and suitable for determination of Baicalin in Qing re jie du Tablets.
