Fatty acid distribution of triacylglycerols and phospholipids isolated from five cultivars of adzuki beans (Vigna angularis) was investigated. Lipids were separated by TLC into eight subfractions. The lipid components comprised mainly phospholipids and triacylglycerols. The phospholipid components included phosphatidylcholine, phoshatidylinositol, and phosphatidylethanolamine. Comparison of these different cultivars showed, with a few exceptions, no significant differences in fatty acid distribution. Fatty acid distribution of triacylglycerols among the five cultivars was characterized as: unsaturated fatty acids predominantly concentrated at the sn-2 position and saturated fatty acids primarily occupying the sn-1 or sn-3 position in the lipids. These results should be useful information to both producers and consumers for manufacturing of traditional adzuki confectionaries(wagashi or an paste) in particularly Japan.
