The analysis methods for the determination of micro or trace elements in high moisture jellyfish were developed. The fatty acid compositions in difderent parts of fresh jellyfish were determined by GC/MS method. Thirty-five fatty acids were identified, 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 other jellyfish also were determined. Amino acids were abundant in R. esculentum jellyfish, especially containing sulfur amino acids, and could be supplied for human diet. The polysaccharide in umbrella part of jellyfish was composed of glucose, galactose and uronic acid, and its molecular weight was 40,000, but the polysaccharide of the oral arms part consisted of glucose, mannose and glycuronic 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 by four species of terricolous pathogenic bacilli and three species of botanic pathogenic fungi. The result demonstrated that the petroleum ether extract had certain bactericidal activity for two species of pathogenic bacilli, and n-butanol extract had certain inhibited activity on apple rot pathogenic fungus.

According to the H NMRstudy, it was found that the protons on the cyclopentadienyl ring of 〓 were not splitted, but when one proton on the cyclopentadienylring was substituted by methyl, that is in〓 complexes, thefour protons on the ring were splitted into four groups,the 〓 between the onesignal and the others is large, the total splitting is over 2ppm. The splittings werealso affected by the halides linked with the titanium, they increase according to theorder of CI, Br, I. By the study of the 〓 Sn NMR, it is found that the chemicalshifts of 〓 are present in low field. It is assume that the large space strain causesthe angles of the tin linked with ligands deviate from the normal tetrahedral anglesresults low field shift for 〓Sn. And by MS study,there were no molecular ions for 〓 complexes in the spectra. However, for 〓 when X=CI,Br,NCO and Ar is tolyl or phenyl group,there were molecular ions,but theirabundances were very small,and no that for the iodide was found.
