Abstract

Fatty acid (FA) distributions and molecular species of triacylglycerols (TAG) isolated from total lipids extracted from adzuki beans (Vigna angularis) were analysed by a combination of AgNO3-TLC and GC, and were investigated in relation to the content of endogenous antioxidants determined by HPLC. δ-Tocopherol was present in the highest concentration (30.5 mg/kg beans), and γ-tocopherol in small amounts (12.8 mg/kg beans). The major lipid components were phospholipids (74.3%), TAG (13.5%), hydrocarbons (4.6%) and steryl esters (4.0%), whilst other components were also present in minor proportions (0.5–1.3%). Seventeen different molecular species were detected. The major TAG components were SMD (5.0%), S2T (19.2%), SD2 (13.7%), SMT (9.3%), MD2 (4.5%), SDT (7.0%), D3 (8.8%) and ST2 (15.8%) (where S, M, D, and T denote a saturated FA, a monoene, a diene, and triene, respectively). These results would be useful to both consumers and producers for manufacture of traditional adzuki foods in Japan.
