Abstract

Present study was designed to evaluate the nutritional values of red skin potatoes collected from
Gujranwala and Lahore regions of Pakistan. Potatoes (Solanum tuberosum) of Gujranwala and Lahore
were found to contain moisture contents of 5.00 and 5.15%, respectively. Fat was 0.19% in S. tuberosum
of Gujranwala whereas Lahore potatoes were found to contain fat 0.2%. Fibre content of S. tuberosum of
Gujranwala was 16.47% while S. tuberosum of Lahore had 13.45% fibre. Protein contents of S. tuberosum
of Gujranwala were 12.89% whereas for S. tuberosum of Lahore were 13.11%. The water extract showed
significant free radical scavenging activities in DPPH radical scavenging antioxidant assay and antioxidant
activity was increased in a dose dependent manner. These results suggest that potato (S. tuberosum) is not
only a cheap source of very important nutritents but also has antioxidant activities which are helpful to
maintain different physiological functions of body.
