【摘要】 目的研究大卫颗粒中绿原酸的含量测定方法。方法采用高效液相色谱法,对大卫颗粒中绿原酸含量进行测定。以Alltima C18(150mm×4.6mm,5μm)为分析柱,流动相为水-甲醇-乙腈-冰醋酸(95∶10∶5∶2);柱温:35℃;检测波长:326nm;流速:1.0mL/min,采用面积外标法。结果绿原酸的含量在10.01～60.06μg线性关系良好,r=0.9999(n=6),平均加样回收率为99.03%,RSD=1.12%(n=6)。结论本方法简便、可靠、重现性好。更多还原

【Abstract】 Objective To study the method of content determination of Chlorogenic Acid in David’s Blunt. Methods The content of Chlorogenic Acid in David’s Blunt was determined by HPLC. Take Alltima C18 (150 mm×4.6 mm, 5 μm) as column, mobile phase was water-methyl acetonitrile-acetic acid glacial (95∶ 10∶5∶2); temperature was 35 ℃; wave-length was at 326 nm; flow rate is 1.0 mL/ min. Results Chlorogenic Acid was linear in the range of 10.01～60.06 μg, r =0.999 9 (n =6). The average recovery rate was 99.03%, RSD=1.12% (n =6). Conclusion The method is simple, credibility, reproducable, and can be used for the quality control of David’s Blunt.更多还原
