Studies on the Isoflavone in Extract of the Flower of Pueraria Lobata by RRLC-Q-TOF MS/MS

Dai Yu-li

Abstract

Rapid resolution liquid chromatography-electrospray ionization mass spectrometry(RRLC-ESIMSn) was applied to identify and differentiate the isoflavone constituents of the flower of Pueraria lobata(Willd.)Ohwi.The data of retention time and molar masses were obtained for the identification of the major isoflavone constituents in the flower of Pueraria lobata(Willd.) Ohwi.The ESI-MSndata of the [M-H]-provide detailed structural information on the isoflavone.Alopecuroides A has been firstly detected from the Pueraria lobata(Willd.) Ohwi.flower.28 components were detected in total from the flower of Pueraria lobata(Willd.) Ohwi..
