摘要: This research aimed to explore the antioxidant activity of microalgae oil through in vitro experiment and investigate the constituents of microalgae oil. The antioxidant activity was determined using the 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging assay, 2,2-Azinobis (3-ehtylbenzothiazolin-6-sulfnicAcid)(ABTS) radical scavenging assay, the reducing power, beta-Carotene bleaching assay and Oxygen Radical Absorption Capacity(ORAC) assay. BHT, alpha-tocopherol or Vc were compared as the reference. It can be confirmed that microalgae oil has moderate antioxidant ability. According to GC-MS analysis, the most abundant compounds in microalgae oil were palmitic acid, docosahexaenoic acid and tetradecanoic, constituting 38.1%, 34.24% and 3.39%, respectively.
