Maytenus ilicifolia is an important plant with potential on cancer treatment and has been
largely used in Brazil and other countries. We have evaluated the crude ethanolic extract of
M. ilicifolia as a potential antioxidant source using an assay based on the bleaching of the
radical monocation 2, 2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid)(ABTS•+) and by
HOCl scavenger capacity. Trolox and uric acid were used as positive controls. The results

Abstract
Maytenus ilicifolia is an important plant with potential on cancer treatment and has been largely used in Brazil and other countries. We have evaluated the crude ethanolic extract of M. ilicifolia as a potential antioxidant source using an assay based on the bleaching of the radical monocation 2, 2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid)(ABTS•+) and by HOCl scavenger capacity. Trolox and uric acid were used as positive controls. The results indicated M. ilicifolia root bark as a great source of antioxidants based on its potential as scavenger of radicals.
