| Outline of Final Research Achievements |
The ethyl acetate soluble fraction of the methanol extract obtained from the defatted seed residue of Jatropha curcas had the same potent antioxidant activities as Trolox. From the antioxidant fraction a catechol-type furofuran lignan, (+)-3,3’-bisdemethylpinoresinol; five catechol-type 1,4-benzodioxane neolignans, (-)-isoamericanol A, (+)-americanol A, 9’-O-methylisoamericanol A, 9’-O-methylamericanol A, and isoamericanin A; and two catechol-type sesquineolignans with furofuran and 1,4-benzodioxane moieties, isoprincepin and princepin were isolated and identified. Potent antioxidant activities of these eight compounds were also confirmed. The ethyl acetate soluble fraction of the methanol extract was found to be more effective than α-tocopherol by the tests for preventing oxidation of commercial salad oil and Jatropha oil and the biodiesel fuels (BDF) derived from the two oils.
