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.
研究了从五种赤豆（Vigna angularis）品种中分离出的三酰基甘油（TAG）和磷脂（PL）的脂肪酸（FA）的区域分布。这些脂质主要由 PL（72.2-73.4wt-%）和 TAG（20.6-21.9wt-%）组成，而其他成分则以较小的比例存在（0.1-3.4wt-%）。在五种品种的豆类中，TAG 和 PL 中 FA 分布的主要特征是：不饱和 FA 主要分布在 sn-2 位，而饱和 FA 主要占据 sn-1 或 sn-3 位。这些结果将为生产者和消费者制造日本传统的赤豆点心（如和果子）提供有用的信息。
