Figure 2

Tocopherol (vitamin E) content in kale (a) and collard (b). Light grey bars, α-tocopherol; dark grey bars, γ-tocopherol. Data are shown as mean ± standard error for the total vitamin E content (). Total vitamin E content in collard was not different among cultivars of kale. Different letters for kale mean significant difference in the total vitamin E content among cultivars by Tukey’s HSD at p ≤ 0.05.
