The concentrations of tocopherols and compositions of fatty acids during germination and maturation of soybean seeds were determined by HPLC and GC. In germination stages, when the length of seedling axis was about 10 ㎝, the contents of total tocopherols and lipids were the highest. At the early phase of pod filling on field condition, the concentration of δ-tocopherol in soybean seeds was the highest, but, in further pod filling, the content of δ-tocopherol decreased continuously, and α- and γ-tocopherol increased. Accumulation of oil during pod filling seems to be determined at the beginning. There seem positive correlations between several tocopherol homologues and fatty acids.
