Abstract

A high-performance liquid chromatographic (HPLC) method with ultraviolet (UV) detector had been developed for simultaneous quantification of danshensu, protocatechuic aldehyde, caffeic acid, salvianolic acid D, rosmarinic acid, salvianolic acid B and salvianolic acid A in Danshen injection. According to the UV spectra of these components, three detection wavelengths have been selected as follows: 280 nm for danshensu and protocatechuic aldehyde, 326 nm for caffeic acid, salvianolic acid D and rosmarinic acid, 286 nm for salvianolic acid B and salvianolic acid A. The limit of detection (LOD) was improved to be in the range of 0.008-0.160 microg/ml. Moreover, excellent linear behavior over the investigated concentration range was observed, with R>0.999 for all the analytes.

摘要

已开发出一种带有紫外(UV)检测器的高效液相色谱(HPLC)方法,用于同时定量测定丹参注射液中的丹酚酸、原儿茶醛、咖啡酸、丹酚酸D、迷迭香酸、丹酚酸B和丹酚酸A。根据这些成分的紫外光谱,选择了三个检测波长,如下所示:丹酚酸和原儿茶醛为280nm,咖啡酸、丹酚酸D和迷迭香酸为326nm,丹酚酸B和丹酚酸A为286nm。检测限(LOD)提高到0.008 - 0.160μg/ml范围内。此外,在所研究的浓度范围内观察到了良好的线性行为,所有分析物的R>0.999。
