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.

建立了 高含水量的海蜇产品中微量、痕量元素成分测定的分析方法；采用 GC/MS 方法测定了新鲜海蜇不同部位的脂肪酸组成，共鉴定出 35 种脂肪酸，其中大多数脂肪酸是首次在海蜇中被检测到，尤其是两种不常见的 C24：5 超长链多不饱和脂肪酸的分析和鉴定在其它水母种属中也从未见报道；海蜇三个部位中氨基酸成分齐全，含量丰富，含硫氨基酸含量较高，可与其它食物蛋白质的氨基酸互补；其中海蜇皮多糖是由葡萄糖、半乳糖和糖醛酸组成，分子量为 40，000，海蜇头多糖是由葡萄糖、甘露糖和糖醛酸组成，分子量为 43，000，以上工作均未见报道；利用石油醚、乙酸乙酯、正丁醇三种不同极性溶剂分别萃取海蜇头乙醇浸提物，用纸碟法和生长速率法分别对四株陆源病原菌和三株植物病原真菌进行了抑菌实验，结果表明海蜇头石油醚提取物和正丁醇提取物具有一定的抑菌活性。
