| Outline of Final Research Achievements |
We have developed a method to isolate and purify amino acids from the natural materials including sediments for radiocarbon measurement. HPLC/fraction collection and the following recrystalization are useful methods for this purpose. Based on the method we have developed, we measured amino acids from known-aged natural samples. The obtained radiocarbon ages are quite consistent with the expected ages. The results suggested that the radiocarbon age of amino acids are useful for the chronological tool.
