[Rapid identification of compounds in cortex moutan by liquid chromatography-tandem mass spectrometry].

Aim null To analyze the chemical constituents of cortex moutan by liquid chromatography coupled with electrospray ionization mass spectrometry. null Methods null An on-line optimized HPLC-DAD/MS2 technique was employed. null Results null In the negative ion detection mode, 38 components such as monoterpene glucosides, galloylglucoses and acetophenones were isolated. Among them, over thirty compounds were identified, including paeonol,...
