| 摘 要： | 比较分析了16种东海沿海贝类的脂肪酸和甾醇组成，通过气相色谱质谱联用法（GC—MS）共检测出26种主要脂肪酸和14种甾醇．结果显示：分类地位相似的贝类基本具有相似的脂肪酸和甾醇组成，瓣鳃纲贝类中PuFA以EPA和DHA为主；腹足纲贝类中PUFA以EPA和ARA为主，EPA含量与瓣鳃纲贝类相当．但DHA含量明显低于瓣鳃纲．甾醇以胆固醇为主，其中瓣鳃纲中胆固醇含量占总甾醇的50％左右，腹足纲中90％左右都是胆固醇，瓣鳃纲中菜油甾醇、菜子甾醇和谷甾醇含量明显高于腹足纲．

| Abstract: | The composition of fatty acid and sterol in 16 coastal shellfishes is analyzed and compared.16 major fatty acids and 14 sterols are detected by GC-MS.The results suggest that shellfish in close taxonomic position have similar composition of fatty acid and sterol.In bivalve both EPA and DHA are identified to be the most important PUFA,while the EPA and ARA act to be the main PUFA in gastropod.The content of EPA in gastropod is found to be similar to that of bivalve,while the content of DHA is much lower than... |
