目的,2,建立冬凌草配方颗粒的超高效液相色谱(UPLC)法指纹图谱,且对冬凌草配方颗粒中多成分含量进行测定。,方法,2,采用沃特世(Waters) ACQUITY UPLC HSS T3色谱柱(2.1 mm×100 mm,1.8 μm),以乙腈、0.1%甲酸水溶液为流动相进行梯度洗脱,流速0.4 mL·min,-1,,检测波长350 nm,柱温为30 ℃,进样量为3 μL。,结果,2,建立了10批冬凌草配方颗粒的指纹图谱,得到8个共有峰,并指认了4个成分峰,分别是咖啡酸、阿魏酸、迷迭香酸、胡麻素,相似度在0.999~1.000之间。4种指标成分在各自浓度范围内呈良好的线性关系(,R,2,=0.999 7~1.000 0),平均加样回收率为90.27%~110.64%,,RSD,为0.07%~2.16%。,结论,2,该法重复性好,稳定可行,符合指纹图谱的分析要求,同时测定4种指标成分的含量作为其质量控制方法。
Objective,2,To establish an ultra high performance liquid chromatography (UPLC) fingerprint of Rabdosiae Rubescentis Herba formula granules and determine the multi-component contents as a quality control method.,Methods,2,Waters ACQUITY UPLC HSS T3 column (2.1 mm × 100 mm,1.8 μ m) was used with acetonitrile and 0.1% formic acid aqueous solution as mobile phase for gradient elution with a flow rate of 0.4 mL ·min,-1,. The detection wavelength was 350 nm, the column temperature was 30 ℃, and the injection volume was 3 μL.,Results,2,The fingerprints of 10 batches of Rabdosiae Rubescentis Herba formula granules were established, 8 common peaks were obtained, and 4 component peaks were identified, namely caffeic acid, ferulic acid, rosmarinic acid and pedalitin, with a similarity of 0.999~1.000. The four components showed a good linear relationship in their respective concentration range (,R,2,=0.999 7~1.000 0). The average recoveries were between 90.27% and 110.64% with ,RSD, of 0.07% ~2.16%.,Conclusion,2,This method has good repeatability, stability and feasibility, meets the analysis requirements of fingerprint, and can determine four components at the same time, which provides a reference basis for establishing the quality control standard of Rabdosiae Rubescentis Herba formula granules.
