摘 要:目的:建立HPLC法同时测定新癀片中8个成分(异嗪皮啶、迷迭香酸、三七皂苷R1、人参皂苷Rgl、人参皂苷Re、人参皂苷Rb1、人参皂苷Rd、吲哚美辛)。方法:采用Agilent ZORBAX SB-C18色谱柱(4.6 mm×250 mm,5μm),以乙腈(A)-0.1%磷酸水溶液(B)为流动相,梯度洗脱(0~30 min,19.5%A;30~60 min,19.5%A→40%A;60~75 min,40%A→45%A;75~90 min,45%A→85%A;90~100 min,19.5%A),流速1.0 m L·min-1,检测波长为203 nm(三七皂苷R1、人参皂苷Rgl、人参皂苷Re、人参皂苷Rb1、人参皂苷Rd)、254 nm(吲哚美辛)和342 nm(异嗪皮啶、迷迭香酸),柱温30℃。结果:异嗪皮啶、迷迭香酸、三七皂苷R1、人参皂苷Rgl、人参皂苷Re、人参皂苷Rb1、人参皂苷Rd和吲哚美辛的线性范围分别为10.09~504.7、10.16~508.2、34.24~1 712、164.6~8 230、27.64~1 382、121.7~6 084、157.7~7 883和274.5~13 724 ng;平均加样回收率(n=3)分别为99.2%~100.3%、101.6%~103.5%、97.6%~98.1%、99.3%~100.7%、96.2%~98.8%、101.1%~102.5%、99.8%~100.8%和101.1%~101.8%,RSD均≤3.0%。3批样品中上述8个成分的含量范围分别为0.38~0.83、0.37~0.83、2.07~2.32、12.40~17.33、1.75~2.64、6.97~11.18、10.85~12.84和19.29~20.80 mg·g-1。结论:该方法操作简单,重复性好,为评价和控制新癀片的质量提供了可靠的方法。Objective: To establish a method for simultaneous determination of eight active ingredients( isofraxidin,rosmarinic acid,notoginsenoside R1,ginsenoside Rg1,ginsenoside Re,ginsenoside Rb1,ginsenoside Rd,and indometaein) in Xinhuang tablets. Methods: The determination was carried out with Agilent ZORBAX SB- C18column( 4. 6 mm × 250 mm,5 μm). The mobile phase consisted of acetonitrile( A)-0. 1% phosphoric acid solution( B)with gradient elution( 0- 30 min,19. 5% A; 30- 60 min,19. 5% A →40% A; 60- 75 min,40% A →45% A; 75- 90 min,45% A→85% A; 90-100 min,19. 5% A) at a flow rate of 1. 0 m L·min- 1. The detection wavelengths were 203 nm for notoginsenoside R1,ginsenoside Rg1,ginsenoside Re,ginsenoside Rb1 and ginsenoside Rd,254 nm for indometaein and 342 nm for isofraxidin and rosmarinic acid. The column temperature was 30 ℃. Results: The calibration curves were linear in the ranges of 10. 09-504. 7 ng for isofraxidin,10. 16-508. 2 ng for rosmarinic acid,34. 24-1 712 ng for notoginsenoside R1,164. 6-8 230 ng for ginsenoside Rgl,27. 64-1 382 ng for ginsenoside Re,121. 7-6 084 ng for ginsenoside Rb1,157. 7-7 883 ng for ginsenoside Rd,and 274. 5-13 724 ng for indometaein. The average recoveries( n = 3) were 99. 2%-100. 3%,101. 6%-103. 5%,97. 6%-98. 1%,99. 3%-100. 7%,96. 2 %-98. 8%,101. 1%-102. 5%,99. 8%- 100. 8% and 101. 1%- 101. 8%,respectively; RSDs were less than 3. 0%.The content ranges were 0. 38-0. 83 mg·g- 1,0. 37-0. 83 mg·g- 1,2. 07-2. 32 mg·g- 1,12. 40-17. 33 mg·g- 1,1. 75-2. 64 mg·g- 1,6. 97-11. 18 mg·g- 1,10. 85-12. 84 mg·g- 1and 19. 29-20. 80 mg·g- 1,respectively. Conclusion: The method is simple and repeatable,which can be applied to the quality control of Xinhuang tablets.
