ABSTRACT
BACKGROUND:
Tocopherols are crucial lipid-soluble antioxidants and essential nutrients. There is increasing interest in the biofortification of crops with vitamin E for reducing micronutrient malnutrition. However, relatively little is known about the development of soybean cultivars with high levels of tocopherol through combined breeding.RESULT:
Tocopherol contents of seeds and germinating seeds of 28 Korean soybean cultivars were analyzed and evaluated for health-promoting activities. Total tocopherol concentrations ranged from 203.9 to 503.1 µg g⻹ in seeds and from 20.1 to 230.1 µg g⻹ in germinating seeds. The traditional landraces of HaNagari (HN, 503.1 µg g⻹), Orialtae (OL, 486.6 µg g⻹), SuMoktae (SM, 476.5 µg g⻹) and SoRitae (SR, 475.5 µg g⻹) showed high levels of tocopherol content. The contents of the four isomers of tocopherol in seeds and germinating seeds were correlated with lipid peroxidation. The γ- and δ-tocopherol contents in seeds were related to 1,1-diphenyl-2-picrylhydrazyl free radical scavenging activity (0.434; P < 0.01 and 0.373; P < 0.05).CONCLUSION:
Total tocopherol content was higher in soybean landraces as compared with modern cultivars developed by cross-breeding. These results suggest that soybean breeding is necessary to increase tocopherol levels.Key words
