内容記述 | Bone is one of the most widely used materials for archaeological dating. It is also relatively difficult to be efficiently pretreated, and so new methods for pretreatment have been tried actively. Ultrafiltration of bone gelatin is thought to be effective in reducing environmental contamination from soil-derived amino acids as well as degraded gelatin or other short-chain proteins in many laboratories. To study effects of this method on ^<14>C age, we analyzed various fractions of collagen (acid-soluble collagen, gelatin, high molecular weight gelatin and low molecular weight gelatin), which are extracted by decalcification and ultrafiltration. We found that the low molecular weight gelatin often has different values of isotope ratios and contents of carbon and nitrogen from the other fractions. Therefore, the low molecular weight gelatin could decrease the precision and the accuracy of ^<14>C dating for bone gelatin. | |||||
