New biological findings of ethanol and chloroform extracts of fungi Suillellus rubrosanguineus and Tylopilus felleus

Abstract The aim of the research was to determine some basic biological activities of less biomedically studied but commonly known two fungi from the Boletaceae family Suillellus rubrosanguineus and Tylopilus felleus, which grow in the forests of Middle Europe. The cytotoxicity tests of the ethanol and chloroform extracts were carried out using NIH-3T3 and MCF-7 cell lines. The presence of alkaloids in the extracts was assessed by the reaction with Dragendorff reagent. In all of the extracts the positive reaction with the reagent was observed. In general, the extracts from Suillellus rubrosanguineus were more cytotoxic than the extracts from Tylopilus felleus and exhibited no selectivity of activities on healthy and cancer cell lines. However, the extracts from Tylopilus felleus proved to be selectively cytotoxic for cancer cell line. Tylopilus extracts or their isolated bioactive compounds could be considered for further study in pre-clinical experiments.
