Values are given in micrograms per 100 gram of sample dry weight basis (μg/100 gdw).Toc: tocopherol; α-TE: α-tocopherol equivalent or content of biologically active vitamin E; values are mean ± standard deviation; n = 3. Values with the different uppercase letter in the same line are significantly () different.
