Significant variations occur in pigmented rice germplasm with respect to their antioxidant potential. Therefore this study was designed to evaluate the antioxidant potential of exotic rice germplasm collected from different parts of the globe. Grain samples of exotic rice germ plasm (21 0 accessions) were collected from different countries of Asia, America and Europe and their ground grain samples were extracted with 80% methanol at 30 oc using sonicater for 30 minutes to estimate their total polyphenol and flavonoids contents and antioxidant activity. Rice germplasm had tremendous variations with respect to total polyphenols (0.0800.71 mg g- 1) and falvonoid contents (0.091 00.413 mg g" 1 ) and antioxidant activity (18096%). Rice cultivars with red and black seed coat had higher antioxidant activity owing to significantly higher polyphenols and falvonoid contents in their grains. Therefore rice cultivars with red and black seed coat color should be included in breeding rice genotypes with higher nutritional value.
