Values are expressed in micrograms per 100 grams 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 letters in the same line are significantly () different.
