Antioxidant Activity and Chemical Constituents of Microalgae Oil of Schizochytrium aggregatum

Abstract:

Abtrast: 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,β-Carotene bleaching assay and Oxygen Radical Absorption Capacity(ORAC)assay. BHT、α-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.
