Extratos brutos de 17 espécies de plantas coletadas em região de Mata Atlântica no Estado de São Paulo (Brasil) foram avaliadas para as atividades: antifúngica, no reparo do DNA e inibição da acetilcolinesterase. Dos 34 extratos obtidos de folhas e galhos das plantas analisadas para a atividade antifúngica com Cladosporium sphaerospermum e C. cladosporioides, 26,5% foram ativos. Todavia, apenas o extrato das folhas de Cabralea canjerana inibiu fortemente o crescimento dos dois fungos. No ensaio de reparo do DNA com linhagens mutantes de Saccharomyces cerevisiae, 11,7% dos extratos foram ativos, sendo que, 100% destes foram seletivos para o mecanismo de reparo do DNA envolvendo topoisomerase II. Das 17 espécies analisadas, 12 demonstraram atividade anticolinesterásica no ensaio qualitativo sobre cromatografia de camada delgada (CCD). No entanto, apenas os extratos de Tetrastylidium grandifolium (galhos) e Sloanea guianensis (folhas e galhos) apresentaram atividade anticolinesterásica maior que 50% no ensaio quantitativo.Crude extracts from 17 plant species collected from an Atlantic Forest region in the State of São Paulo (Brazil) have been screened for antifungal, DNA-damaging and acetylcholinesterase inhibiting activities. of the 34 extracts obtained from leaves and stems of plants assayed for antifungal activity with Cladosporium sphaerospermum and C. cladosporioides 26.5% were active. However, only the extract of leaves of Cabralea canjerana showed a strong inhibition of both fungi. The DNA-damaging assay with mutant strains of Saccharomyces cerevisiae resulted in 11.7 % of the extracts being active whereas 100% of them showed selectivity for the DNA-repair mechanism of topoisomerase II. of the 17 species analysed, 12 showed anticholinesterasic activity in TLC assay. However, only extracts from Tetrastylidium grandifolium (stems) and Sloanea guianensis (leaves and stems) inhibited acetylcholinesterase activity more than 50% in quantitative assay
