文摘
- •
Pyrolysis-GC-MS was performed on archaeological bone collagen extracts.
- •
There were clear diagenetic effects on collagen composition.
- •
Diagenesis causes depletion in diketopiperazines production.
- •
There were signs of selective preservation of (H)Proline, Phenylalanine and Alanine.
- •
Pyrolysis fingerprint and diagenesis show no relation with δ13C and δ15N ratios.
