Abstract:
In this study, squid liver oil was extracted by water and amount of water in the extraction was determined. The fatty acids of the oil were analyzed by gas chromatography-mass spectrometry. And its antioxidation effect in vitro was also determined, including DPPH free radical scavenging, superoxide anion radical scavenging, hydrogen peroxide scavenging capabilities and inhibition effect on lipid peroxidation. Besides, thin-layer analysis and full wavelength scanning analysis showed that the extracted crud squid liver oil contained astaxanthin. It provided a theoretical basis for the application of squid liver in food, medicines and feed.
