HPLC法同时测定复方丹参口服液中羟基红花黄色素A和丹酚酸B的含量

摘要

目的:建立同时测定复方丹参口服液中羟基红花黄色素A和丹酚酸B含量的方法.方法:采用高效液相色谱法.色谱柱为SHIMADZU ODS-C18,流动相为甲醇-0.5%磷酸(35:65,V/V),流速为1.0 ml/min,检测波长为403 nm(羟基红花黄色素A)、286 nm(丹酚酸B),柱温为35℃,进样量为20μl.结果:羟基红花黄色素A、丹酚酸B检测质量浓度线性范围分别为2.01~20.10、39.80~398.00μg/ml(r均为0.999 9);精密度、稳定性、重复性试验的RSD<2%;加样回收率分别为98.26%~101.25%、98.70%~101.35%,RSD分别为0.94%、0.71%(n=9).结论:该方法简便可行、重复性好,可用于复方丹参口服液中羟基红花黄色素A和丹酚酸B的含量测定.%OBJECTIVE:To establish a method for simultaneous determination the contents determination of hydroxysafflor yel-low A and salvianolic acid B in Compound danshen oral solution. METHODS:HPLC was performed on the column of SHIMADZU ODS-C18 with mobile phase of methanol-0.5% phosphoric acid (35:65,V/V) at flow rate of 1.0 ml/min,dection wavelength was 403 nm for hydroxysafflor yellow A and 286 nm for salvianolic acid B and column temperature was 35 ℃, the volume injection was 20μl. RESULTS:The linear range was 2.01-20.10μg/ml for hydroxysafflor yellow A(r=0.999 9)and 39.80-398.00μg/ml(r=0.999 9) for salvianolic acid B. RSDs of precision,stability and reproducibility tests were lower than 2%;recoveries were 98.26%-101.25%(RSD=0.94%,n=9)and 98.70%-101.35%(RSD=0.71%,n=9),respectively. CONCLUSIONS:The method is feasible and reproducible,and can be used for the contents determination of hydroxysafflor yellow A and salvianolic acid B in Com-pound danshen oral solution.
