Aim: The study evaluated the chemical contents and antioxidant potential of aqueous extract of Irish
potato tubers traditionally used for ulcer treatment in Nigeria.
Methods: Freshly harvested Irish potato tubers were purchased from Aba grocery market, Abia
State. They were thoroughly washed in running water, peeled, sliced and dried in an oven at 60ºC to
a constant weight. The dried potatoes were milled into fine powder (flour) and extracted using water
as the solvent. The proximate, mineral, phytochemical and vitamin contents as well as antioxidant
potentials were determined using standard methods.
Results: The results of the proximate analysis showed that the extract contain high percentage of
carbohydrate (76.39±4.06%) followed by crude fat (11.43±0.75%) while crude protein (0.82±0.07%)
is the least nutritional composition. Magnesium, sodium and iron contents are high in the extract,
but calcium and copper were absent. The extract also contain high amounts of phenols
(15.54±0.21%), flavonoids (13.03±1.59%), saponins (8.09±0.43%) and alkaloids (4.46±0.91%), but
low in antinutrients. Total antioxidant capacity of the extract was 40.16±1.25 mg/AAE/g, with
  vitamins A, C and E contents being 3.56±0.01 mg/100 g, 61.78±12.48 mg/100 g and 20.39±0.11 µg/100 g respectively.

Conclusion: The results of the present study indicate that Irish potato tubers have high
phytochemical content and possess antioxidant potential substantiating its use traditionally in the
treatment of stomach ulcers.
