LC-ESI-MS method was used to analyze the formed di-and tri-peptide hi the reaction system of N-(O,O-diisopropyl)phosphoryl aspartic acid and adenosine.Ouster ions of the peptides were given hi the ESI-MS.The structures of these small peptides were confirmed by LC-MS-MS analysis.Compared with the traditional HPLC-UV detection,this method showed good sensitivity and selectivity for peptide in the presence of compounds with strong UV absorption,such as nucle-oside and nucleotide.

Compared with the traditional HPLC-UV detection, this method showed good sensitivity and selectivity for peptide in the presence of compounds with strong UV absorption, such as nucleoside and nucleotide.
