The analysis methods for the determination of microor trace elements in high moisture jellyfish were developed. The fatty acid compositions indifderent parts of fresh jellyfish were determined by GC/MS method. Thirty-five fatty acids wereidentified, and most of them were found in R. esculentum jellyfish for the first time. Especially,two unusual very long chain polyunsaturated fatty acids that were never detected in the otherjellyfish also were determined. Amino acids were abundant in R. esculentum jellyfish, especiallycontaining sulfur amino acids, and could be supplied for human diet. The polysaccharide inumbrella part of jellyfish was composed of glucose, galactose and uronic acid, and its molecularweight was 40,000, but the polysaccharide of the oral arms part consisted of glucose, mannose andglycuronic acid, and its molecular weight was 43,000. Above-mentioned data were never reported.The ethanolic extract of oral arms part of jellyfish were extracted by different polar solvents(petroleum ether, acetic ether, n-butanol), and antibacterial activity was tested to these extracts byfour species of terricolous pathogenic bacilli and three species of botanic pathogenic fungi. Theresult demonstrated that the petroleum ether extract had certain bactericidal activity for twospecies of pathogenic bacilli, and n-butanol extract had certain inhibited activity on apple rotpathogenic fungus.
