The amount of alkaloids and
oxalates present in some selected Nigerian food samples were
determined. The samples include Solanum tuberosum L.,
Ipo-mea batatas L.,
Discorea alta, Discorea rotundata, Colocasia esculents
L., Triticum vulgare, Soja hispida and Amarathus
sp. The percentage alkaloids
present in the samples ranged from 11.4 - 29.5% while that
of oxa-lates range from 20 - 92 mg
per 100 g of fresh weight sample. Sol. tubero-sum
L. has the highest alkaloid content while Amarathus
sp. has the highest oxalate content. There is a positive
correlation between the alkaloid content and oxalate content
in the food samples analyzed.
Key words:
Alkaloids, oxalates, gravimetric, titremetric. |
