The toxicants and phosphorus content of some Nigerian vegetables.
The oxalate, hydrocyanic acid, phytic acid and phosphorus contents of twelve leafy vegetables were determined. The values ranged from 47.7-194.3 mg/100 g DM, 4.32-23.8 mg/100 g DM, 90-260 mg/100 g DM and 215-1110 mg/100 g DM, respectively. The ratio of phytic acid to phosphorus ranged from 13.9-90.7. The leaves contained low levels of hydrocyanic acid, while the oxalate, phytic acid and phosphorus contents were high. The results are discussed in terms of their clinical implications and nutritive values.
