The significant perturbation of the mitosis process of the tumoral cells, as well as the profound diminution of the cell viability of the neoplastic cell cultures argue the behaviour of some polysaccharidic and polyphenolic extracts as in vitro active cytostatic and cytotoxic agents. This primary characterization of some natural fungal or vegetable extracts as cytostatic and/or cytotoxic agents offers the informational background for the introduction of those biopreparations in the in vivo antitumoral screening program on different experimental tumoral systems. %U http://www.gbm.bio.uaic.ro/index.php/gbm/article/view/720
