Abstract：Oxidation stabilities of oil and its biodiesel of D.Salina, Chlorella, and Spirulina were investiga-ted respectively.The results showed that the peroxide value and acid value increased with the increasing of heat-ing temperature, with the heating temperature prolonged, peroxide value of D.Salina biodiesel increased gradu-ally, acid value increased slightly in the first 4 days, and viscosity increased slowly; and anti-oxidants had some inhibiting effects on oxidation of D.Salina oil, the analysis of fatty acid methyl ester showed that linolenic acid methyl ester content of D.Salina biodiesel decreased during heating process at 110℃, and there were small changes of the content of other acid methyl esters.
