This study aimed to determine the alpha-tocopherol content in seven Thai indigenous rice varieties from northern Thailand and compare their antioxidant potential. The rice varieties studied were Doi, Khanhi, Hengor Leothin, Riceberry, Khao Niew Kam, Man Pu, and Khao Chao Mali. Alpha-tocopherol was extracted using 95 percent ethanol, n-heptane, and sodium sulfate. The results showed that Khao Niew Kam had the highest alpha-tocopherol content (0.25 mg per 100 g), followed by Hengor Leothin and Man Pu (0.13 mg per 100 g). The lowest content (0.01 mg per 100 g) was found in Doi, Riceberry, Khao Chao Mali, and Khanhi rice.
