  To the best of our knowledge, this is the first study to use liquid chromatography/multistage mass spectrometry to demonstrate the distribution of eight vitamin E homologs in plants. Many tocopherol homologs, which showed higher antioxidant activity than tocotrienol homologs, were discovered and α-tocopherol, which had the highest antioxidant activity among these homologs, was widely distributed in all plants. In addition, α-tocopherol occurred at high concentrations in the leaves of plants belonging to the sumac family, which is native to tropical regions. Furthermore, 25.9% of plants contained α-tocopherol alone, whereas the remaining 74.1% contained α-tocopherol in combination with other homologs. The detection frequency was the highest for a combination of α-tocopherol and γ-tocopherol, which is a precursor of α-tocopherol in plants. The h.. View More»
