Abstract:

Endogenous tocopherols in extracted lipids from Jack beans (Canavalia gladiata DC.) were determined by high-performance liquid chromatography (HPLC), and were investigated in relation to the fatty acids (FA) distribution of triacylgycerols (TAG) and phospholipids (PL). The dominant tocopherols were (δ)-tocopherol (78.9-96.5mg%) and (γ)-tocopherol (42.1-56.1mg%) with much smaller amounts of (α)-tocopherol (1.1-1.3mg%). The lipids of Jack beans comprised mainly TAG (34.6-38.6 wt.%) and PL (54.8-57.4 wt.%), and other components were also detected in minor proportions (0.3-3.8 wt.%). The PL components included phosphatidyl choline (46.2-48.7 wt.%), phosphatidyl inositol (23.4-29.6 wt.%) and phosphatidyl ethanolamine (18.5-21.2 wt.%). Comparison of these different beans showed, with a few exceptions, no significant differences (P>0.05) in FA distribution. The FA distribution of TAG among the five beans was evident in the Jack beans: unsaturated FA (93.3-95.3 wt.%) were predominantly concentrated at the sn-2 position and saturated FA (33.6-34.4 wt.%) primarily occupying the sn-1 position or sn-3 position. The results obtained from this work would provide useful information to both producers and consumers for manufacturing functional foods or beverages in Japan and elsewhere.
