説明

Soybean oil containing α-tocopherol (3 × 10-9 mol/g) was used for determining the antioxidant activity of various ascorbyl fatty acid esters. They were incubated at 33°C and their proxide values were determined.<BR>Antioxidant activity of 6-monoesters were significant at lower concentrations of 10-7 M and 10-8 M, and its activity was not significant at higher concentrations of 10-4M and 10-5 M.<BR>Chain length of fatty acid of ascorbyl 6-monoesters had no significant effect on the antioxidant activity.<BR>Among the various lauroyl ascorbic acid esters 6-monoester had the highest antioxidant activity, but 2-monoester had no activity and had rather a proxidant effect. 2, 6-diester, 2, 5, 6-triester and 2, 3, 5, 6-tetraester seemed to have a slight antioxidant activity.<BR>6-monolauroyl-AsA by itself had also the antioxidant activity on the autoxidation of methyl linoleate without α-tocopherol and its activity with α-tocopherol added at the same level as soybean oil increased to about the same level as soybean oil.
