摘要
目的:建立测定丹七片中丹参素和原儿茶醛含量的 HPLC 方法。方法:采用 Diamonsil^(TM) C_(18)柱(5 μm,4.6 mm×200mm),以甲醇-1%醋酸溶液(3:97)为流动相,流速1.0 mL·min^(-1),以丹参素钠和原儿茶醛为外标物,检测波长为281 nm。结果:丹参素钠和原儿茶醛进样量分别在0.3~10.0 μg和0.03~1.3 μg范围内呈良好线性关系,丹参素钠和原儿茶醛的平均回收率(n=6)分别为99.3%(RSD=1.8%)和98.4%(RSD=1.5%)。结论:本方法快速、简便、准确。
Objective:To establish an HPLC method for the determination of danshensu and protocatechuic aldehyde in Danqi tablets. Methods:The column was Diamonsil^TM C18 (5μm ,4. 6 mm × 200 mm), methanol- 1% acetic acid(3: 97) as mobile phase at a flow rate of 1.0 mL ·min^-1 and sodium danshensu and protocatechuic aldehyde as external standard,wavelength of the detector was 281 nm. Results:The linear ranges were 0. 3 -10.0μg(r = 1. 000) for sodium danshensu, 0. 03 - 1.3 μg ( r = 1. 000) for protocatechuic aldehyde. The average recoveries ( n = 6) were 99. 3% ( RSD = 1.8% ) for sodium danshensu ,98. 4% ( RSD = 1.5% ) for protocatechuic aldehyde. Con. elusion:The method is rapid, simple and accurate.
