Abstract

Ten pigmented landraces of rice were analyzed for chemical composition and antioxidant properties. The results of proximate composition and calcium iron zinc content showed intra variability among landraces. The amylose total anthocyanin (TAC) and phytate contents were found to be in the range of 22.01 - 44.38 28.73 - 193.36 mg cyanidin-3-glucoside/100 g and 1.16 - 24.49 mg Fe/100 g respectively. Total phenol and polyphenol contents were in the range of 233.92 - 251.38 mg ferulic acid equivalent/100 g and 252.43 - 284.36 mg gallic acid equivalent/100 g respectively. Antioxidant assays of landraces showed free radical scavenging activity.
