Qualitative and quantitative analyses of Chrysanthemum morifolium ‘Fubaiju’ by LC-MSn and HPLC-UV / 中国药科大学学报

ABSTRACT

@#A qualitative analytical method of liquid chromatography coupled with mass spectrometry(LC-MSn)was developed for the identification of main constituents in Chrysanthemum morifolium ‘Fubaiju’. High-performance liquid chromatography(HPLC)was developed for the quantification of five active components, including chlorogenic acid(1), luteolin-7-O-β-D-glucopyranoside(2), luteolin-7-O-β-D-glucopyranuronide(3), 3, 5-Di-caffeoylquinic acid(4), and apigenin-7-O-β-D-glucopyranoside(5). A total of 22 compounds, including 13 flavonoids and 9 phenolic acids, were identified based on their retention behaviors, UV profiles and MS fragment information. Furthermore, a validation method with good linearity(r> 0. 999 9), precision, stability, repeatability and recovery was successfully applied for simultaneous determination of five major components in 10 batches of C. morifolium ‘Fubaiju’ by HPLC-UV method. The established method was proved to be a validation strategy for the quality evaluation of C. morifolium ‘Fubaiju’.
