The 10 samples of different rice were collected from Ashraf road firdos bazaar Peshawar and were tested for glycemic indices, total starch content, free radical scavenging activity, and amylose to amylopectin ratio. The glycemic indices were in the range of 72.88 ±1.70 to 89.08 ±6.19, and total starch content from 7 to 35.1%. The free radical scavenging activity of Basmati Chawal 18.46±0.33 (lowest) to Mota Chawal 44.98±2.02 (highest). The Amylose to Amylopectin ratio was from 0.12 to 1.822. The highest Amylose to Amylopectin ratio was of Seela Lazat (1.822) and the lowest one was of Seela Dakra Dobar (0.12). The sample of lowest glycemic index was Seela Dakra Dobar (72.88 ±1.70) and the highest was Mota Chawal (89.08 ±6.19). The DPPH method was followed for the measurement of antioxidant activity. The %inhibition of DPPH activity by an antioxidant was in the range of 18.46±0.33 to 44.98±2.02 for 100μg/ml. Conclusion: The research performed was to determine radical scavenging activity, Glycemic Index Starch content and Amylose to Amylopectin ratio for different rice varieties. A variety which has high radical scavenging activity, low Glycemic index and high Amylose Content will be a good variety to use to be healthier. That variety should be preferred for diabetic patient.
