Among the native fruits, Garcinia genus is composed of many fruit species used by traditional medicine. Since there are no reports in the literature about the chemical composition of the false mangosteen (Garcinia cochinchinensis), the present study was aimed to perform the physicochemical screening and analysis of the presence of phytochemicals in the fruit pulp of this plant. Analysis of titratable acidity, soluble solids and pH were performed in the fresh fruit and vitamin C, anthocyanins and carotenoids in fresh, dehydrated and frozen fruit after 30, 60 and 90 days. Moreover, qualitative tests to check the presence of phytochemical compounds were also performed. Fresh fruit showed average values of 4.88 ± 0.061 for titratable acidity (g/100g of citric acid), 12.3 ± 0.265 for soluble solids (°Brix) and pH 2.52 ± 0.067. The average values for Anthocyanins and total carotenoids did not differ among fresh and frozen samples, but there was significant reduction in the levels of Vitamin C. Dehydrated fruit exhibited significantly higher levels of Carotenoids and Vitamin C compared to the fresh fruit, but lower values of Anthocyanins. Colorimetric analysis revealed the presence of phenols, flavonols, flavanones, flavanonols, xanthones and alkaloids in dehydrated G. cochinchinensis fruit.
