Abstract:

Phytochemical screening showed that mangosteen peel contains alkaloids, flavonoids and terpenoids. Extract of total flavonoids were 22.03 g and total terpenoids were 7.89 g that obtained through partition extraction. While the extracts of total alkaloids were 9.61 g. Antioxidant test was carried out using the DPPH free radical capture method using UV-Visible spectroscopy at a maximum wavelength of 515 nm. Based on the linear regression obtained IC50 values for total alkaloids were 89.15 mg/L, total flavonoids were 22.24 mg/L and total terpenoids were 26.71 mg/L. Total flavonoids and total terpenoids from mangosteen peel were the compound that has the greater antioxidant then total alkaloids.
