Abstract:: In the competition experiment，the non—covalent complexes was studied by electrospray ionizationmass spectrometry between the same protein lysozyme and two different kinds of chrysin phosphorylated derivatives，such as Ca and Ce，Cb and Ce，Cc and Ce，Cd and Ce．It was found that，in spite of all of compoundscontaining phosphoryl group，there were differences among them．The interaction lysozyme and chrysin一7一phosphated amino acid esters(a，b，c，d)was stronger than that of chrysin一7一diisopropyl phosphate(e)．
