dc.descriptionMany diseases and related degenerative processes including heart, câncer and Parkinson diseases are associated with rcactive oxygen species (ROS). In an effort Io preveni diseases, search for com-pounds with antioxidant activity hás been a major interestof dif-ferent research groups in natural products research. The objective of this research was to investigatethe antioxidant activity of EtOH leaf extract ofjacarando decurrrens and its fractions using the 2,2-diphenyl-2-picrylhydrazyl hydrate (DPPH) assay [lJ, that uses s pé ciro me t ric method to determine radical scavenging activity, Rutinattheconcçntrationof l.Omg-L was used as the standard. Our results ha vê shown lhat crude extract and fractions had anti-oxidant activities mainly if tested at concentrations of 5.0 to 10.0mg-L. such activities, however. were lesser or equal to the standard (Table 1). The triterpenes, ursolic and oleanohc acids, were detected in the crude extract, Jd-1 and Jd-2, Possibly, these triterpenes are the active constituents responsible for the antioxi-dant activity |2j. At lower concentrations (0,6mg-L than the standard. Jd-3 fraction was the most active. The presenceof flavo-noids and glycosilated compounds were detected in jcl-3 fraction (2], This is the first attempt to demonstrate antioxidant activities found i n Já cara n (ia decurrens leaf extracts.
