Objective Lipids and 19 kinds of main fatty acid compositions of 19 species marine shellfish from Zhanjiang coast were investigated by GC-MS. Methods Based on Kang's method to deal with sample,and using GC-MS to detect the content of lipid. Results Lipid contents of 19 species marine shellfish were 0.08%~0.59%. Saturated fatty acid(SFA),monounsaturated fatty acid(MUFA) and polyunsaturated fatty acid(PUFA) were reached to 32.75%~62.35%,1.55%~22.79% and 22.31%~57.32%,respectively. Based on fatty acid result,n-3 PUFA had high ratio in 19 species marine of shellfish. Especially,EPA and DHA contents in 3 species of Cephalopod were higher than that in other shellfish,EPA and DHA reached to 0.518~1.004g and 0.402~1.377g,respectively. Conclusion Nineteen species of shellfish are belong to low fat and high PUFA organism. The ratio of n-6/n-3 PUFA in three class,gastropod (1.00~14.34) is higher than bivalve(0.16~0.65)and cephalopod(0.12~0.44),therefore,cephalopod mollusks is better than other 16 species shellfish as the resource to supplement the n-3 PUFA. Combined with classification characters and biology character of shellfish,the results of fatty acid data showed that a certain extent relationship between fatty acid content and classification of 19 species marine shellfish.
