Bioactive extracts and chemical constituents of two endophytic strains of Fusar...
Nascimento,Andréa M. do; Conti,Raphael; Turatti,Izabel C. C.; Cavalcanti,Bruno C.; Costa-Lotufo,Letícia V.; Pessoa,Cláudia; Moraes,Manoel O. deEthyl acetate extracts of cultures grown in liquid Czapek and on solid rice media of the fungal endophyte Fusarium oxysporum SS46 isolated from the medicinal plant Smallanthus sonchifolius (Poepp.) H. Rob., Asteraceae, exhibited considerable cytotoxic activity when tested in vitro against human cancer cells. Chromatographic separation yielded anhydrofusarubin (1) and beauvericin (2) that were identified based o...
Contribution for the phytochemical studies of Ageratum fastigiatum
Gonçalves,Lucas D.; Almeida,Hugo R.; Oliveira,Patrícia M. de; Lopes,Norberto P.; Turatti,Izabel C. C.; Archanjo,Fernando C.; Grael,Cristiane F. F.Organic extracts from leaves plus branches plus inflorescences of Ageratum fastigiatum (Gardner) R. M. King & H. Rob., Asteraceae, were fractionated through classic chromatography. The steroids stigmasterol, chondrillasterol and campesterol were isolated from hexane extract. The triterpenes lupeol, taraxasterol, α-amyrin, β-amyrin, pseudotaraxasterol, lupeol acetate and α-amyrin acetate were isolated from e...
Antimicrobial activity of Aegiphila sellowiana Cham., Lamiaceae, against oral p...
Ferreira,Marcele A.; Carvalho,Tatiane C.; Turatti,Izabel C. C.; Furtado,Niege A. J. C.; Martins,Carlos H. G.; Lopes,Norberto P.; Cunha,Wilson R.The antimicrobial activity of Aegiphila sellowiana Cham., Lamiaceae, against oral pathogens is reported. The Minimal Inhibitory Concentrations (MICs) for inhibiting the microorganisms growth were determined using the broth microdilution method from the CLSI M7-A7 protocol. Chlorhexidine was used as the positive control. The ethanol crude extract of the aerial parts of A. sellowiana exhibited activity against th...
