Abstract

|
|
Octopus Octopus vulgaris was dried with open air at 17∼20℃ for 90 hours. Nucleotides and related substances were collected by extraction with cold perchloric acid, and their amounts were determined by ion exchange column chromatography.
The contents of inosine, hypoxanthine and ADP in raw sample were 9.4, 5.1 and 4.1 μmole/g dry wt. respectively. ATP and AMP were very low in content. But IMP was not detected in Octopus muscle.
ATP, ADP and inosine tended to degrade rapidly during sun drying while AMP and hypoxanthine were increased. Especially, hypoxanthine were increased about three times during sun drying and also it was increased about two times during three months storage after sun drying.
