Abstract: Regiospecific distributions of fatty acids (FA) of triacylglycerols (TAG) and phospholipids (PL) isolated from five cultivars of adzuki beans (Vigna angularis) were investigated. The lipids comprised mainly PL (72.2–73.4 wt-%) and TAG (20.6–21.9 wt-%), whilst other components were detected in minor proportions (0.1–3.4 wt-%). The principal profiles of the FA distribution in the TAG and PL were evident in the beans among the five cultivars: unsaturated FA were predominantly distributed in the sn-2 position, whilst saturated FA primarily occupied the sn-1 or the sn-3 position in the these lipids. The results would be useful information to both producers and consumers for manufacturing traditional adzuki confectionaries such as wagashi in Japan.
