摘 要:目的:建立反相HPLC同时测定白花蛇舌草口服液中3,4-二羟基苯甲酸甲酯(Ⅰ)、对香豆酸(Ⅱ)、阿魏酸(Ⅲ)和反式6-0-对香豆酰鸡屎藤苷甲酯(Ⅳ)的含量。方法:采用Diamonsil^TM C18柱(4.6mm×250mm,5μm);流动相A乙腈,B甲醇-水-冰醋酸(5:95:0.25),梯度洗脱:0~20min,1%~16%A;20~42min,16%A;42~46min,16%~20%A;46~65min,20%A。检测波长265nm;流速1.0mL·min^-1。结果:Ⅰ,Ⅱ,Ⅲ与Ⅳ分别在2.1~105(r=0.9998),3.5~175(r=0.9998),1.72~86(r=0.9999),4.0~200mg·L^-1(r=1.0000)线性关系良好,方法平均回收率分别为99.9%,97.9%,98.6%,98.1%。结论:方法简便快速、准确度高,可用于白花蛇舌草口服液中4种组分的同时测定。Objective: A new method for simultaneous determination of four methyl-3, 4-dihydroxybenzoate (Ⅰ), P-coumaric acid (Ⅱ) , ferulaic acid (Ⅲ) and E-6-O-P-coumaroyl scandoside methyl ester ( Ⅳ ) in Hedyotis diffusa oral solution by reversedphase HPLC was developed. Method: The separation was performed on a DiamonsilTM C18 column (4. 6 mm×250 mm, 5μm) with gradient elution. A-acetonitrile, B-methonal-water-glacial acetic acid (5:95: 0. 25 ), 0-20 min, 1%-16% A; 20-42 min, 16% A; 42- 46 min, 16%-20%A; 46-65 min, 20%A. The UV detection was set at 265 nm; flow rate 1.0mL·min^-1. Result: There was good linearity between the peak area and concentration at the ranges of 2. 1-105 ( r = 0. 999 8 ), 3.5-175 ( r =0. 999 8 ), 1.72-86 ( r = 0. 999 9), 4.0-200mg·L^-1 ( r = 1.000 0) for Ⅰ , Ⅱ, Ⅲand Ⅳrespectively. The average recoveries of Ⅰ , Ⅱ, Ⅲand Ⅳ were 99. 9%, 97.9%, 98. 6% and 98.1%. Conclusion: The method is rapid, simple and accurate, and it can be used for the evaluation of H. diffusa oral solution.
