1、人參皂苷Rg1及Rb1。方法 采用SHIMADZU Shim-pack XR-ODS Ⅲ(2.0 mm×75 mm, 1.6 μm)色譜柱;以乙腈-水作為流動相進行梯度洗脫;體積流量為0.4 mL/min;檢測波長為203 nm;進樣體積為3 μL。結(jié)果 三七皂苷R1、人參皂苷Rg1及Rb1分別在0.025 7~0.257 0、0.101 2~1.012 0、0.104 4~1.044 0 μg與峰面積呈良好的線性關(guān)系,平均加樣回收率分別為96.7%、98.1%、98.8%。結(jié)論 本方法在15min內(nèi)可以將三七皂苷R1、人參皂苷Rg1及Rb1有效分離,節(jié)省了大量人力和流動相的消耗,為中藥的質(zhì)量控制技術(shù)提供參考方法。;Objective To establish the quantitative method of notoginsenoside R1, ginsenosides Rg1 and Rb1 in Compound Danshen Tablet by ultra-fast liquid chromatography (UFLC). Methods This assay was performed on Shimadzu Shim-pack XR-ODS Ⅲ (75 mm × 2.0 mm, 1.6 μm) column with acetonitrile-water as mobile phase in gradient elution at a flow rate of 0.4 mL/min; And the detection wavelength was 203 nm. The injection volume was 3 μL. Results The linear of notoginsenoside R1, ginsenosides Rg1 and Rb1 had good linearity within the range of 0.025 7—0.257, 0.101 2—1.012, and 0.104 4—1.044 μg. And their average recovery ratios were 96.7%, 98.1%, and 98.8%. Conclusion UFLC method may greatly improve the separation efficiency and analysis speed in the case of notoginsenoside R1, ginsenosides Rg1 and Rb1 in Compound Danshen Tablet while reducing the solvent consumption. As an alternative of conventional HPLC, UPLC is more convenient, fast, and feasible."/> 1;人參皂苷Rg1;人參皂苷Rb1;UFLC;Compound Danshen Tablet;notoginsenoside R1;ginsenoside Rg1;ginsenoside Rb1"/>
