摘  要:目的建立运用HPLC法同时测定肿节风提取物中绿原酸、异嗪皮啶和迷迭香酸含量的方法。方法采用Agilent ZORBAX Eclipse XDB—C18(4.6mm×250mm,5μm)色谱柱;流动相:乙腈(A)-0.1%甲酸(B),梯度洗脱0~30min,5%→20%A;30~40rain,20%→25%A;40~60rain,25%→29%A;60~65min,29%→32%A;流速:1mL·min^-1;检测波长:330nm;柱温:30℃;进样量:20μL。结果绿原酸、异嗪皮啶、迷迭香酸分别在0.0280~0.448μg(r=0.9998)、0.0164—0.262μg(r=0.9999)、0.113—1.81μg(r=0.9999)范围内呈良好的线性关系;平均回收率(n=6)分别为103.4%(RSD=2.77%)、98.3%(RSD=2.58%)、95.2%(RSD=2.49%)。结论该法简便快速,重复性好,准确可靠,可用于同时测定肿节风提取物中绿原酸、异嗪皮啶、迷迭香酸的含量.Objective To establish a method for simultaneous determination of chlorogenic acid, isofraxidin and ros-marinic acid in the extract of Sarcanclra glabra(Thunb.) Nakai. Methods The three components were separated on a Agilent ZORBAX Eclipse XDB-CIs column(4.6 mm × 250 mm, 5 μm) with a flow-rate of 1 mL·min^-1 at 30 ℃. The mobile phase consisted of acetonitrile and 0.1% formic acid. The gradient condition was A: 5 %→20 % from 0 to 30 rain, A: 20 %→25 % from 30 to 40min, A: 25 %→29 % from 40 to 60 min, A: 29 %→32 % from 60 -65min. The detection wavelength was set at 330 nm and the injection volume was 20 μL. Results The linear ranges of chlorogenic acid, isofraxidin and rosmarinic acid were 0.0280-0.448 μg(r=0.9998), 0.0164-0.262 μg (r=0.9999), 0.113-1.81 μg(r=0.9999), respectively. The mean recoveries (n=6) of chlorogenic acid, isofraxidin and rosmarinic acid were 103.4 %(RSD=2.77 %), 98.3 %(RSD=2.58 %), 95.2 %(RSD=2.49 %), respectively. Conclusion The established method is simple, reproducible, and accurate, and can be used for the simultaneous determination of chlorogenic acid, isofraxidin and rosmarinic acid in the extract of Sarcandrae glabra.
