摘要
目的:建立复方丹参片中三七皂苷R1、人参皂苷Rgl、人参皂苷Rbl的含量测定方法。方法:采用超高效液相色谱法,色谱条件:ThermoScientificHypersilODSC18(150.0mm×2.1mm,3μm)色谱柱;流速为0.2mL·min-1;柱温30℃;检测波长203nm;进样量1μL;以乙腈(A)和水(B)为流动相梯度洗脱:0rain(20%A)→10min(39%A)→12min(46%A)→15min(20%A)。结果:复方丹参片中三七皂苷R1、人参皂苷Rgl、人参皂苷Rbl分别在0.0216—0.4320μg、0.045—0.900μg、0.0302~0.6040μg范围内呈良好的线性关系;平均加样回收率分别为97.28%、97.58%、97.77%。结论:该方法高效、快速、准确,可为复方丹参片的质量控制提供参考。
Objective:To establish the assay method of notoginsenoside R1, ginsenoside Rgl and ginsenoside Rbl in Fufang Danshen tab- lets by ultra high performance liquid chromatography. Methods: Using Thermo Scientific Hypersil ODS C18 (150 mm × 2. 1 mm, 3 μm), flow rate is O. 2 mL · min-1 ;Column temperature is 30 ℃ ;Detection wavelength is 203 nm;Sample quantity is 1 μL;with aceto- nitrile (A) and water(B) as mobile phase gradient elution :0 min (20% A) →10 min ( 39% A) → 12 min ( 46% A) →15 min ( 20% A ). Results :notoginsenoside R1, ginsenoside Rgl and ginsenoside Rbl respectively had good linear relationship with the scope of 0.021 6 - 0. 432 0 μg,0. 045 -0. 900 μg,0. 030 2 -0. 604 0 μg. The average recoveries were 97.28% ,97.58% ,97.77% respectively. Conclu- sion:The method is efficient,rapid and accuracy ,which can orovide reference for the aualitv control of Fufan~ Danshen Tablets.
