Abstract
This invention discloses characteristic peptides of deer antler glue and their application in the identification of deer antler glue products. When using liquid chromatography-tandem mass spectrometry (LC-MS / MS) in electrospray ionization positive ion mode for multiple reaction detection, the precursor ion of the characteristic peptides of this invention is 854.07, and the daughter ions are 858.43 and 630.34; or the precursor ion is 408.21, and the daughter ions are 556.32 and 449.30; or the precursor ion is 786.82, and the daughter ions are 772.33 and 657.30. The characteristic peptides of this invention can identify and characterize deer antler glue, and based on this, a rapid detection method using characteristic peptide ion pairs as indicators (HPLC-MS / MS) can be established. Furthermore, the method of this invention can rapidly and sensitively identify deer antler glue and its products, providing support for the market application and promotion of deer antler glue.
