Abstract :

In order to evaluate the potential of medicinal effects of the popular edible Pulicaria jaubertii in Yemen, the chloroform (CH[Cl.sub.3]), ethylacetate (AcOEt) and n-butanol (n-BuOH) extracts from leaves were investigated using a model system. AcOEt extract which had high level of polyphenols and flavonoids, exhibited the most potent antioxidant capacity in each assay, showing a high dose dependant manner scavenging radical activity ([DPPH.sup.o]), lipid peroxidation inhibition ([Fe.sup.2+]/Ascorbate system), OH radical quenching (Deoxyribose assay), ferrous chelating capacity and a moderate reducing power ([Fe.sup.3+]-[Fe.sup.2+]) compared to the n-BuOH extract which proved a moderate effect, and to CH[Cl.sub.3] which was the weakest extract. This study suggested that the differences of the potency of the antioxidant activity may be explained by the differences in the polyphenol and flavonoid levels. Key words: Pulicaria jaubertii, Polyphenols, flavonoids, antioxidant activity.
