Abstract
Free Radicals are substances that derive from incompletely oxidized compounds that can damage cells and cause inflammatory diseases, atherosclerosis, cancer, and aging. Plants are known as a source of medicines that are being developed by researchers, such as temurui (Murraya koenigii L. Spreng) which collected from Langsa, Aceh. Temurui or curry leaves, a plant that is usually used as a cooking spice by Aceh people, were extracted using maceration method with n-hexane, ethyl acetate, and methanol, respectively. Methanolic extract of temurui showed very strong DPPH scavenging activity with the IC50 value of 77.818 ppm. This activity was contributed by secondary metabolites contained in that plant, such as alkaloids, terpenoids, saponins, flavonoids, and tannins. This plant have great potent to develop as new drugs, especially new antioxidant drugs.
