Black rice was reported to be a rich source of antioxidant: two-fold stronger than blueberries and six times higher than the regular white rice with respect to antioxidant activities. As according to the American Chemical Society 2010 report, one spoon of black rice contains the same amount of anthocyanin as a spoon of fresh blueberries. This is attributed to a large amount of anthocyanins contained in its aleurone layer. Anthocyanins are flavonoids that perform as antioxidants in the body. The anthocyanin components in the black rice are about 26.3%, of which cyanidin-3-glucoside and peonidin-3-glucoside are 90%. Apart from anthocyanins, black rice is rich vitamin E which present in the bran.

Anthocyanins from the black rice has attracted substantial interest due to its anti-diabetic effect.
