Methanol extracts of seven edible fruits found in southern Brazil: Garcinia achachairu, Rubus imperialis, Rubus rosaefolius, Solanum quitoense, Solanum sessiliflorun, Diospyros inconstans and Plinia glomerata, were evaluated for their total phenol content and antioxidant activity in different in vitro free radical scavenging models. In addition, studies were performed on cell viability of extracts of the seeds of G. achachairu against murine melanoma cells. The fruits peel and seeds of G. achachairu were very promising in terms of total phenol content (data in gallic acid equivalent per gram), as assessed by the Folin-Ciocalteu method, with values of 9.70 +/- 3.2 and 8.40 +/- 1.1, respectively. On the other hand, antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl scavenging assay showed that the fruit pulp and peel of P. glomerata presented the best profile, with values of the 16.3 +/- 1.8 and 15.9 +/- 2.4 mu g/ml, respectively. Regarding the cytotoxic effect of methanol extract and guttiferone A from G. achachairu, we have observed that both inhibit the growth of B16F10 tumor cells, with calculated IC50 values of 49.6 +/- 2.1 mg/ml and 48.6 +/- 5.4 mM, respectively.
