Abstract
Caffeine neither causing didn't decrease the risk of cancer, yet it used just to note the activity of cytochrome P-4501A2 (CYP1A2) by converting into its metabolite i.e., paraxanthine. The purpose of the present study was to determine the caffeine and its metabolite phenotypes and their relation to cancer risk in healthy female volunteers of local population in Pakistan. The average value of metabolic ratio [(1,7-dimethylxanthine (17X) and Caffeine 1,3,7-trimethylxanthine (137X)] was found to be 1.182995 ± 0.21137. BMI (used to categorize into different groups, i.e., overweight, underweight etc.) of all volunteers were found to be 19.93Kg/m2. Retention time was 15 and 37 min for 1,7-dimethylxanthine (17DMX) and 1,3,7 trimethylxanthine (137TMX), respectively.
