Present study was designed to evaluate the nutritional values of red skin potatoes collected fromGujranwala and Lahore regions of Pakistan. Potatoes (Solanum tuberosum) of Gujranwala and Lahorewere found to contain moisture contents of 5.00 and 5.15%, respectively. Fat was 0.19% in S. tuberosumof Gujranwala whereas Lahore potatoes were found to contain fat 0.2%. Fibre content of S. tuberosum ofGujranwala was 16.47% while S. tuberosum of Lahore had 13.45% fibre. Protein contents of S. tuberosumof Gujranwala were 12.89% whereas for S. tuberosum of Lahore were 13.11%. The water extract showedsignificant free radical scavenging activities in DPPH radical scavenging antioxidant assay and antioxidantactivity was increased in a dose dependent manner. These results suggest that potato (S. tuberosum) is notonly a cheap source of very important nutritents but also has antioxidant activities which are helpful tomaintain different physiological functions of body.
