Outline of Final Research Achievements

For the extraction of novel bioactive peptides, ordinary and routine methods using water-extraction combined with acid have been established and employed so far on animal tissues. In the present study, I sought novel bioactive substances in avian and mammalian tissues and tested several organic solvents for the efficient extraction. It was revealed that some bioactive peptides with hydrophobic properties which have been known in the previous studies were identified using dimethyl sulfoxide (DMSO), although I could not find a novel bioactive substance. I found that a novel extraction method using DMSO is suitable for the identification of highly hydrophobic substances.
