The salivary peptidomics provides a new method for study of disease biomarkers, but the effect of frozen storage conditions on analysis results is not very clear. In this study, we separated and enriched these peptides in human saliva by graphene-lanthanide phosphate composite nanomaterial (LaGM), then identified them by nano-liquid chromatography-high resolution tandem mass spectrometry. The salivary samples were analyzed after these samples were stored at -20℃ and -80℃ for six months respectively. We identified 429 peptides which belong to 33 proteins at -80℃ and 595 peptides corresponding to 31 proteins at -20℃. In comparison with the sample stored at -80℃, the "new" saliva peptides were mainly from the degradation of existing peptides. In addition, some salivary proteins also had a degree of degradation after stored at -20℃. In peptide sequence level, this study illustrated that frozen storage conditions had effects on salivary peptidome, suggesting that saliva sample should not be stored at -20℃ for long time when used to analyze peptidomics. This method can provide reference for relevant medical research.
