Última Activity of the aqueous extract from Polymnia sonchifolia leaves on growth and production of aflatoxin B1 by Aspergillus flavus BJM Pinto,Marina M.; Gonçalez,Edlayne; Rossi,Maria H.; Felício,Joana D.; Medina,Cláudia S.; Fernandes,Maria J.B.; Simoni,Isabela C.. The aqueous extract from Polymnia sonchifolia leaves (AE) was tested for inhibitory activity on aflatoxin B1(AFB1) production and growth of Aspergillus flavus. The cytotoxicity of AE on Vero cells was also performed. Suspensions of A. flavus spores were inoculated into 50 mL of YES medium together with different concentrations of the AE. The aflatoxin B1 was extracted, analyzed by thin layer chromatography and quantified by photodensitometry. All the concentrations of AE induced inhibition of AFB1 production. The aqueous extract showed in vitro cytotoxicity to Vero cells only at concentrations above 500 µg/mL.

Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822001000200011 Cytotoxicity of subfractions and compounds from Polymnia sonchifolia BJM Fernandes,Maria Judite B.; Limas,Caroline; Rossi,Maria Helena; Gonçales,Edlayne; Simoni,Isabela C.. Our previous works showed that extracts and fractions from Polymnia sonchifolia had presented an inhibitory activity on growth and aflatoxin production by Aspergillus flavus in non-cytotoxic concentrations. In this work, report results on the in vitro cytotoxicity of subfractions and of a mixture of sesquiterpenes lactones from Polymnia sonchifolia on Vero cells. The cytotoxicity was assayed through crystal violet staining (CVS) method and the 50% inhibitory concentration for cell growth (IC50) was calculated. Both subfractions and the mixture of sesquiterpenes lactones did not show in vitro cytotoxicity to Vero cells on active biologically concentrations against production of aflatoxin B1 by Aspergillus flavus.
