Extrative Electrospray Ionization Tandem Mass Spectrometry of Apigenin
摘要
Abstract
The extractive electrospray ionization tandem mass spectrometry (EESI-MS") of apigenin was studied using both positive and negative ion modes. The results showed that the detection of apigenin was more sensitive in negative ion mode than that in positive ion mode. By comparing EESI-MS spectra with electrospray ionization mass spectrometry( ESI-MS) spectra of apigenin, we found that EESI mode is softer than ESI mode. The mechanism of the fragmentation of apigenin was also discussed in detail based on the experimental collision-induced dissociation(CID) data recorded in these experiments, and was confirmed by the ESI-MS. The study is useful for the rapid and direct determination of trace amount of apigenin in complex matrix by EESI-MS.关键词
