Fat-soluble vitamin contents of okra pods.

Varieties	S	K	M	D
Tocopherol (vitamin E) (mg/100 g DW)	1.47±0.06^a	0.98±0.09^b	0.76±0.24^c	0.15±0.02^d
Menaphthone (vitamin K3) (mg/100 g DW)	0.20±0.02^a	0.11±0.02^b	0.21±0.01^c	0.05±0.00^d
Retinol (vitamin A) (𝜇g/100 g DW)	ND	ND	ND	ND
Cholecalciferol (vitamin D3) (𝜇g/100 g DW)	ND	ND	ND	ND
𝛽-Carotene (𝜇g/100 g DW)	ND	ND	ND	ND

Each value is presented as the mean ± standard deviation (𝑛=3). Data with different superscript letters in the same column of variety indicate significant difference (𝑃<0.05) as analyzed using Duncan’s multiple range test. Dry weight (DW) was not detected (ND). Tocopherol (E) and menaphthone (K3) are expressed in mg per 100 g. Retinol (A), cholecalciferol (D3), and 𝛽-carotene are expressed in 𝜇g per 100 g.
