Abstract: Oil-resin of Copaifera multijuga Hayne is popularly used due to its anti-inflammatory properties. In this study, we evaluate the effects of the bark ethanolic extract on Ehrlich tumor cells. For extract preparation, bark was removed from stem and chopped into smaller pieces. Most were dried and grounded. The first extract was made with hexane, followed by ethyl acetate. Absolute ethanol was added to the residue and extract was filtered and concentrated (EtOH). In vitro cytotoxic activity of the EtOH was analyzed on both spleen and tumor cells. For evaluation of in vivo activity, Ehrlich carcinoma bearing Swiss mice were daily treated with different concentration of EtOH during 30 days..............
