摘要:
目的 建立HPLC法测定清热消肿口服液中绿原酸的含量。 方法 采用phenomenex Luna -C18柱(200 mm×4.60 mm, 5 μm),流动相为甲醇-1%冰醋酸(20：80),流速为1.00 ml/min,检测波长326 nm,柱温为30 ℃。 结果 绿原酸进样量在0.163 1~1.087 2 μg范围内与峰面积线性关系良好,r=1.000(n=5),平均回收率为100.40%,RSD为1.20%(n=9)。 结论 该方法简便、准确、可靠、重现性好,可用于该制剂的质量控制。
Abstract:
Objective To develop a HPLC method for determining the content of Chlorogenic acid in QingRexiaozhong Oral Liquid. Methods The phenomenex Luna-C18(200 mm×4.60 mm ,5 μm)was used ;the mobile phase consisted of water-1%Acetic acid (20：80),the flow rate of 1.00 ml/min,and the detecting wavelength was 326 nm.The column temperature was at 30 ℃. Results There was a good linearity for Chlorogenic Acid in the range of 0.163 1~1.087 2 μg, r=1.000(n=5),and the average recovery rate was 100.40%, RSD=1.20%(n=9). Conclusions The method was simple,accurate,reliable and reproducible,which could be available for the quality control of QingRexiaozhong Oral Liquid
