摘  要:目的建立同时测定茵陈中芦丁、金丝桃苷、异槲皮苷、4,5-O-二咖啡酰奎宁酸、异鼠李素-3-O-葡萄糖苷含量的方法,为茵陈药材的质量控制提供依据。方法采用RP-HPLC法。色谱柱:Luna C18柱(250mm×4.6mm,5μm);流动相:乙腈-体积分数0.04%磷酸水溶液(体积比17:83);检测波长:345nm。结果芦丁、金丝桃苷、异槲皮苷、4,5-O-二咖啡酰奎宁酸、异鼠李素弓一O-葡萄糖苷质量浓度分别在0.942~18.84mg·L^-1(r=0.9995)、1.190~23.79mg·L^-1(r=0.9995)、1.107~22.14mg·L^-1。(r=0.9994)、56.78~1.136×10^3mg·L^-1。(r=0.9990)、0.6219~12.44mg·L^-1(r=0.9998)内与峰面积呈良好的线性关系(n=5);方法回收率(n=9)分别为98.1%、100.7%、98.4%、100.2%、101.7%。结论该方法可用于茵陈药材的质量控制。Objective To establish a method for simultaneous determination of rutin, hyperin, isoquercitrin, 4,5-O-dicaffeoyl quinic acid and isorhamnetin-3-O-glucoside in Herba Artemisiae Capillariae. Methods A RP-HPLC method detected by UV wavelengths of 345 nm were developed. The system consisted of a C18 column(250 mm×4.6mm,5 μn) taking a mixture of acetonitrile and 0.04% phosphoric acid as the mobile phase. Results The linear response range was 0. 942 0 - 18.84mg·L^-1( r = 0. 999 5 ), 1. 190 - 23.79 mg·L^-1(r=0.9995),1.107-22.14mg·L^-1(r=0.9994),56.78-1.136×10^3mg·L^-1(r= 0. 999 0) and 0.621 9 - 12.44mg·L^-1( r = 0. 999 8 ), respectively ( n = 5). The average recoveries ( n = 9) of rutin, hyperin, isoquercitrin, 4,5-O-dicaffeoyl quinic acid and isorhamnetin-3-O-glucoside were 98.1%, 100.7% ,98.4%, I00.2% and 101.7%, respectively. Conclusions The assay demonstrates that the method has adequate accuracy and selectivity to measure the five chemical constituents in Herba Artemisiae Capillariae.
