摘 要:采用反相高效液相色谱法,色谱柱为DiamosilC18(4.6mm×250mm,5μm),以甲醇(A)-0.5%磷酸水溶液为流动相,梯度洗脱(0-20min,43%A;20~30min,43%A-61%A;30-60min,61VoA),流速1.0mL·min^-1检测波长为350nm,柱温30℃,进样量20μL,建立同时测定蒙药复方述达格-4中高良姜素、槲皮素、芦丁的高效液相色谱含量测定方法.结果表明高良姜素、槲皮素、芦丁的线性范围分别为1.06~10.6μg(r=0.9999),0.0276~0.276pg(r=0.9999),0.0264~0.264μg(r=0.9999);平均加样回收率(72—6)分别为98.71%,97.66%,98.13%.本法准确、简便,具有良好的重复性.An HPLC method for simultaneous determination of Galangin, Quercetin, Rutin in shudage-4 Mongolian Medicine compounds was developed. The separation was performed on a Diamosil C18 (460 mm× 250 mm, 5μm) column by Methanol (A)-0. 5% phosphoric acid(B) (0 - 20 min,43A;20-30min,43 A→61% A;30-60 min,61% A)as the mobile phase at a flow rate of 1.0 mL · min^-1. The detection wavelength was set at 350 nm,and the column temperature was 30 ℃. The calibration curves of Galangin,Quercetin,Rutin were linear in the ranges of 1.06-10.6μg (r= 0. 9999) ,0. 0276-0. 276μg (r-=0. 9999)and 0. 0264-0. 264 μg (r=0. 9999)respectively The mean recoveries(n=6)of them were 98.71% ,97.66% and 98.13% respectively. The developed method is simple,accurate, reliable, and is helpful to the exploitation for Traditional Mongolian Medicine shudage-4.
