Abstract

Gae-bul, Urechis unicinctus, fresh or sun-dried has been esteemed as one of the most tasty sea foods in Korea. In this paper, the degradation of nucleotides and their related compounds in Gae-bul during sun drying was studied. The nucleotides and their related compounds were extracted with cold perchloric acid and their amounts were determined by anion exchange column chromatography. In fresh Gae-bul, the results showed that AMP was dominant and the content of ATP, ADP, AMP and inosine were 0.6, 3.5, 6.8 and $0.7{\mu}\;mole/g$ on dry base respectively while IMP was not detected. AMP tended to degrade slowly and ATP and ADP decreased rapidly while inosine ana hypoxanthine increased remarkably sun drying. In dried sample, the content of AMP was the highest, $5.6{\mu}\;mole/g$ on dry base, whereas ATP, ADP, inosine and hypoxanthine were lower.

개불, Urechis unicinctus, 건조중의 핵산관계물질의 변화를 음이온교환칼럼크로마토그래피로 실험하여 다음과 같은 결과를 얻었다. 살아있는 개불에는 AMP가 건물량기준으로 $6.8\mu\;mole/g$ 로서 가장 함량이 높았고, IMP는 존재하지 않았다. 건조중 ATP, ADP, AMP는 감소하고 inosine과 hypoxanthine은 증가하였으나, AMP이외의 다른 pattern은 함량이 적고 개불에서와 마찬가지로 건조한 개불에 있어서도 AMP가 건물량기준으로 $5\mu\;mole/g$로서 함량이 가장 많았다.
