Water-soluble vitamin contents of okra pods.

Varieties	S	K	M	D
Riboflavin (vitamin B2) (𝜇g/100 g DW)	ND	ND	ND	ND
Niacin (vitamin B3) (𝜇g/100 g DW)	1.42±0.42^b	7.21±0.47^b	22.70±8.69^a	7.65±0.68^b
Pyridoxine (vitamin B6) (𝜇g/100 g DW)	49.81±4.02^a	17.90±7.42^c	37.93±6.29^b	11.50±0.31^c
Cobalamin (vitamin B12) (𝜇g/100 g DW)	ND	49.56±18.55^b	91.20±20.64^a	34.54±3.69^b
Ascorbic acid (vitamin C) (mg/100 g DW)	12.51±0.06^c	11.60±0.21^c	27.14±2.46^a	15.62±0.05^b

Each value is presented as the mean ± standard deviation (𝑛=3). Data with different superscript letters in the same column of variety indicate a significant difference (𝑃<0.05) as analyzed using Duncan’s multiple range test. Dry weight (DW) was not detected (ND). Riboflavin (B2), niacin (B3), pyridoxine (B6), and cobalamin (B12) are expressed in 𝜇g per 100 g. Ascorbic acid (C) is expressed in mg per 100 g.
