Abstract
INTRODUCTION
Ginseng Flos (GF), the flower bud of Panax ginseng, is a worthy functional food with medicinal potential. A few studies have focused on the comprehensive and systematic analysis of its major bioactive constituents.
OBJECTIVE
The aims are to develop the methods of ultra-fast liquid chromatography coupled with triple quadrupole-time of flight tandem mass spectrometry (UFLC-Triple TOF-MS/MS) and ultra-fast liquid chromatography coupled with triple quadrupole-linear ion trap tandem mass spectrometry (UFLC-QTRAP-MS/MS) for the qualitative and quantitative analysis of the saponins in GF.
METHODOLOGY
UFLC-Triple TOF-MS/MS and UFLC-QTRAP-MS/MS were established for the qualitative and quantitative analysis of the saponins in GF, separately.
RESULTS
Fifty-one saponins were identified in GF using UFLC-Triple TOF-MS/MS method; among them, 21 saponins were characterized by comparing with standards. Furthermore, 12 ginsenosides (ginsenoside Re, Rg1 , Rf, 20(S)-Rg2 , 20(R)-Rg2 , Rb1 , Rc, Ro, Rb2 , F1 , Rd, and F2 ) were synchronously determined by UFLC-QTRAP-MS/MS method after the extraction with 70% methanol. This UFLC-QTRAP-MS/MS method showed good linearity (r >0.9991), the interday and intraday precision, repeatability and stability were all satisfied, the average recoveries of standard addition for the compounds were between 94.01% and 105.16%, and the relative standard deviations were less than 5%.
CONCLUSION
The results are available for the comprehensive quality control and assessment of GF and its relative products.
