Abstract:

An ultra-high performance liquid chromatography (UPLC) coupled with electrospray quadrupole time-of-flight mass spectrometry (ESI-qTOF-MS) method was developed for the rapid separation and identification of the components in Phryma leptostachya L.. The samples were eluted on an ACQUITY UPLC HSS T3 C18 column (2.1 mm×100 mm, 1.8 μm) with a gradient of 0.1% formic acid (solvent A) and acetonitrile (solvent B) as the mobile phases at a flow rate of 0.25 mL/min. The chromatographic analysis of Phryma leptostachya L. by UPLC-qTOF-MS/MS identifies the characterization of 47 compounds, 15 of which are clearly identified by comparison with reference standards. For quantitative analysis, 15 major compounds are simultaneously detected in 12 batches of Phryma leptostachya L. samples using UPLC-DAD at 210 nm, 260 nm and 326 nm. The method is validated in terms of precision, reproducibility, stability and accuracy. In conclusion, this study provides a potential method for the overall quality control of Phryma leptostachya L..
