Abstract The genus Swietenia (Meliaceae) contains various secondary metabolites, such as flavonoids, limonoids, and other antioxidant compounds. In this study, the antioxidant capacity is evaluated together with the phenol and flavonoid contents of the seeds extracts of Swietenia mahagoni. The antioxidant potential of different extracts of S. mahagoni seeds has been determined by the reduction power of DPPH, FRAP, hydrogen peroxide scavenging tests. The methanol extracts of the seeds of S. mahagoni showed the highest phenol and flavonoid content and reduction capacity, while the hexane extracts showed the lowest level of reduction capacity. The antioxidant potential of S. mahagoni seeds extracts is strongly related (P<0.02) to the phenol content of methanol extracts. Catechin, which is used as a control, shows the greatest antioxidant strength in this study. The results show significant antioxidant activity and high concentrations of phenol compounds and flavonoids in the S. mahagoni seeds extracts. Some constituents of the active fractions were detected by chromatography, and were characterized by NMR.
