1-Methylsalsolinol 1, dopamine 2, quercetin 3, isorhamnetin 4 and quercetin 3-O-robinobioside 5 were isolated for the first time from ethanolic extract of Hammada scoparia (Pomel) Iljin. The complete NMR analysis of compound 1 was reported. The scavenging activity of the pure compounds 1-5 against DPPH (2, 2-diphenyl-1- picrylhydrazyl) was investigated. Results showed that quercetin, 1-methylsalsolinol and dopamine presented a potent antiradical activity in comparison with ascorbic and caffeic acids. The chemical composition of hexanic extract obtained from the leaves of this plant, was analysed by GC-MS. This analysis led to the identification of 35 constituents.
