The chemical examination of methanolic extract of the plant, L. citriodora yielded two known compounds; oleanolic acid (1) and saccharose (2). The structures of the compound were established based on physical and chemical data (UV, IR, 1H and 13C NMR and mass) and also co-comparison with an authentic compounds. The crude extract, fractions and isolated compounds were studied for elastase inhibition and dendrite elongation activity. The compound, oleanolic acid showed good elastase inhibition activity
