Abstract—The main physico-chemical composition of four mao cultivars (cv.) (Antidesma thwaitesanum Müell.; Fah-pra-tann, Sann-home, Kham-ta, Heuy-bang) were investigated. The cv. Fah-pra-tann and Kham-ta had the highest sugar content (193.58, and 190.90 g/L), with the lowest acidity (6.55, and 6.76 g/L). The sugar acid ratio represent the balance taste ranging from 13.72 to 30.02. The cv. Fah-pra-tann and Kham-ta were in appropriate range of sugar x pH2 (238, and 226). The main acid was citric (5.02-10.98 g/L), and tartaric (3.36-5.51 g/L) acids. They were rich in phenolic (349.18-845.97 μgGAE/ml), anthocyanin (583.07-2361.42 mg/l), and antioxidant activity (290.71-1213.80 μgQEAC/ml), being inversely proportional to colour intensity (6.16-8.39), and were highest in the cv. Kham-ta. They had similar contribution to the colouration between yellow and red pigments, and correlated with the results for the tint and anthocyanin of the juices. It indicates that mao had desirable characteristics to produce beverage products.
