Establishment of UPLC fingerprint and determination of multi⁃index components of Rabdosiae Rubescentis Herba formula granules
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.
