Antioxidants are compounds that inhibit the oxidation processes and protect cells from the harmful effects of free radicals. Phytochemical and antioxidant activity screening has been done to 31 types of fruits peel extract. Phytochemical screening performed to determine the pharmacological active ingredient such as: alkaloids, steroids and triterpenoid, flavonoids, saponins and phenolic especially those with antioxidant activity. Phytochemical screening performed by standard methods while antioxidant activity using 1-1-diphenyl-2-picrihydrazil (DPPH). Result showed that the chemical compounds of avocado fruit peel extract and mangosteen positive for alkaloids, steroid-triterpenoids, flavonoids, saponins and phenolic.
