S. Anbuselvi and T.Balamurugan
ABSTRACT
Manihot esculenta and Ipomoea batatas (L.) Lam., are major industrial
crop in Tamil nadu which are rich in antioxidants and lot of therapeutic
application. The phytochemical components suchasalkaloids, saponin,
tannins, steroids, anthocyanins, flavonoids and anthroquinones and
biochemical constituents were extracted using different solvents
namely ethylacetate, methanol, chloroform and acetone. Specific
antinutrients are extracted more in methanol and ethyl acetate solvents
other than ethanolic extract. The oxalate and trypsin inhibitors were
highly observed in sweet potato. Phytate was found to be 235mg/100g
of cassava. Cyanogenic glycosides and phlobatanins were only present in cassava and
coumarin was extracted in sweet potato.
Keywords: sweet potato, cassava, antinutrients, phytochemicals.
