Extraction and analysis of polyunsaturated fatty acid from Asterina pectinifera in Huanghai Sea
摘要
Abstract
The full fats of Asterina pectinifera in Huanghai Sea were extracted and refined using solvent extraction combined with silica gel column chromatography with yield of 1.64 %. The full fats were analyzed by gas chromatography and the result indicated that the full fats from Asterina pectinifera contained abundant Polyunsaturated Fatty Acid (PUFA) with a total of 25 kinds, especially rich in EPA and DHA. After enrichment by silica gel column chromatography, the total PUFA content in ligarine fraction is 42.20%, in which EPA and DHA account for 12.50% and 10.33% respectively. The total PUFA content in acetic ether fraction is 48.98%, in which EPA and DHA take up 17.53% and 6.59% respectively. The total amount of EPA and DHA in both fractions all exceeded that of the fish oil from deep sea. In conclusion,the Asterina pectinifera in Huanghai Sea is a favorable source of PUFA.关键词
