以反相高效液相色谱法测定中药靖巅饮口服液中阿魏 酸的含量。色谱柱: Shim pack_ C L C_ O D S (6 ×150 m m , 5 μm ) ; 流动相: 甲醇 - 二 氯甲 烷 - 水- 冰 乙 酸 (37 .5∶2 ∶60 ∶0 .5 ) ; 检 测 波长: 313 n m ; 流 速:0 .5 m L/ min ; 柱温 25 ℃。阿 魏酸 在 0 .0484 ~1 .2100 μg 范 围内 具有 良 好的 线 性关 系, r = 0 .9990 , 回 收率 为97 .47 % , R S D= 3 .24 % 。
The content of ferulic acid in the Jingyeyin Oral Liquid was determined by RP-HPLC. Column: Shim pack_ C L C_ O D S (6 × 150 m m , 5 μm) ; Mobile phase: Methanol-dichloromethane-water-glacial acetic acid (37 .5:2 :60 :0.5) ; Detection Wavelength: 313 n m ; Flow rate: 0 . 5 m L/min; Column temperature 25 °C. Ferulic acid in 0 . 0484 to 1. There is a good linear relationship in the 2100 μg range, r = 0 . 9990, the recovery rate is 97. 47%, R S D= 3 . 24%.
