| Veränderung des Tocochromanolmusters einiger Pflanzenöle (Sojabohne, Lupine, Sonnenblume und Weizen) während Keimung und Wachstum Alteration of Tocochromanol Pattern in Some Plant Oils (Soybean. Lupine. Sunflower and Wheat) during Germination and Growth  | | | | Abstract
| Seed, sprout and plant oils from soybean (Soja hispida), lupine (Lupinus mutabilis), sunflower (Helianthus annuus) and wheat (Triticum aestivum) were assayed for their tocochromanol content and composition. High-performance liquid chromatography (HPLC) with fluorescence detection was used to determine tocopherols and tocotrienols of laboratory-extracted oils. In general, leaves of lupine, soja, and wheat with a high chlorophyll-a-content also were found to be rich of alpha-tocopherol; roots contained very little or no tocopherol. Contents of gamma-and delta-tocopherol in soja and lupine decreased during germination and growth, whereas the alpha-tocopherol concentration increases significantly. This evidence suggests that non-alpha-to-copherols might be methylated enzymatically to alpha-tocopherol. Tocochromanol pattern of wheat also changes characteristically in an analogous manner during plant development. Germ i nation of sunflower seeds also resulted in a conversion of beta-and gamma-tocopherols and in a slight decrease of the predominantly occurring alpha-tocopherol. In relation to the lipid content, the concentration of total tocopherols in oil plants increases significantly during growth. Possible implications for the biosynthesis of tocochromanols are discussed. | | | |
