Anthocyanin is not only the common natural color, but also has potential applications such as the antioxidant component, and many other health benefits. This pigment has good application in the food industry. Purple rice (Oryza sativa) is a special cereal in Vietnam, and some other Asian countries. This rice contains high anthocyanin (~0.4%). The anthocyanin extraction was evaluated, and the best method of the extraction was determined. The experiment was conducted with the following variables: ethanol-to-water ratio as solvent (E/W, 1:9-6:4) (v/v), purple rice-to-water ratio (P/W,1: 6-1:16) (w/v), solvent pH (pH, 2.0–3.0), solvent temperature (ST, 30–70 °C) and extraction time (ET, 60–180 min). The result showed that the best adequate extraction conditions were E/W, 2:8; P/W, 1:10; pH, 2.2; 60oC; and ET, 90min. At such condition, 116.7 ± 5.8 mg / 100g anthocyanin was extracted.
