Última Free radical scavenging activity of ethanolic extracts from herbs and spices commercialized in Brazil BABT Mariutti,Lilian Regina Barros; Barreto,Gisela Pizarro de Mattos; Bragagnolo,Neura; Mercadante,Adriana Zerlotti. Ethanolic extracts from 23 different dried herbs and spices commercialized in Brazil were investigated for their free radical scavenging properties using the stable free radicals 2,2'-diphenyl-β-picrylhydrazyl (DPPH•) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS•+), and Trolox as reference (TEAC) for both radicals. The kinetic curves for both radicals showed to follow the first order kinetics model and the decay rate constant (k obs) was calculated. For all the samples, the two methods showed a good linear TEAC correlation, indicating that the average reactivity of the compounds present in the ethanolic extracts was similar. Sage and rosemary extracts showed the highest free radical scavenging capacities, while onion showed negligible...

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132008000600018 The relationship between fungi growth and aflatoxin production with ergosterol content of corn grains BJM Castro,Maria Fernanda Penteado Moretzsohn de; Bragagnolo,Neura; Valentini,Sílvia Regina de Toledo. The relationships between fungal growth and ergosterol content and between aflatoxins B1 and B2 production and ergosterol content were verified in corn grains. In the first experiment, fungal growth and ergosterol content were monitored during incubation of corn grains presenting water activities of 0.85a w and 0.92a w at 25ºC over a period of 18 days. For the Taiúba variety, the fungi growth and ergosterol content increased more rapidly for 0.92a w than 0.85a w. Maximum ergosterol levels were 2.8 and 4.6 µg/g, respectively, for 0.85a w and 0.92a w. For the Cargill hybrid 606, a more pronounced increase in fungal growth was verified just at the end of the incubation period, mainly for 0.92a w when an acentuated increase in ergosterol content was also...
