Identification study of glue medicines / 中国药学杂志

ABSTRACT

OBJECTIVE: To find the marker peptides of five kinds of glue medicines including deerhorn glue, tortoise shell glue, donkey-hide gelatin, bovine-hide gelatin, and pig-hide gelatin. METHODS: The characteristic peptides of different gelatins were identified by tripsin digestion and HPLC-MS/MS. RESULTS: The marker peptides of five glue medicines were found, ie, donkey-hide gelatin m/z 539.8, deerhorn glue m/z 765.4, tortoise shell glue m/z 631.3, bovinehide gelatin m/z 641.3, pig-hide gelatin m/z 774.5, and the methods which can be used to identify the glue medicines were established according to the marker peptides. CONCLUSION: The marker peptides that we found can be used for the identification of glue medicines.
