摘  要:目的:建立高效液相色谱法(HPLC)测定大黄棱莪颗粒剂中黄芩苷含量方法。方法:采用Nova—pakC18(250mm×4.6mm,10μm),黄芩苷流动相是甲醇-水-磷酸(47:53:0.2),检测波长为280nm,流速为1mL· min^-1,柱温25%。结果:该方法线性范围为4~20μg·mL^-1,r=0.9998,平均回收率为98.8%(RSD=1.5%,n=5)。结论:本方法测定大黄棱莪颗粒剂中黄芩苷含量简便准确,结果稳定。OBJECTIVE:A HPLC method for the determination of a baicalin in Dahuanglinge Granules was established. METHODS : Nova - pakC 18 (250 mm x 4.6 ram, 10 μm) column Was used with methanol - water - 0.2 % phosphoric acid (47:53:0.2) as mobile phase. Content Was detected at a wavelength of 280 nm with the column temperature at 25℃ and flow rate 1 mL·min^- 1 RESULTS : The linear range was 4 - 20 μg· mL^- 1 for baicalin with r = 0. 999 8. The average recovery rate was 98.8 %, RSD = 1.5 % ( n = 5 ) for baicalin. CONCLUSION : The method Was simple and accurate. The result is stable.
