Screening of brazilian plants for the presence of peroxides
Extratos clorofĂłrmicos ou diclorometĂąnicos de 357 espĂ©cies vegetais de ocorrĂȘncia no sul do Brasil foram testados quanto Ă presença de perĂłxidos, atravĂ©s de cromatografia em camada delgada, utilizando o reagente de detecção de Huber & Fröhlke. Das espĂ©cies testadas, 71 (20%) apresentaram resultado positivo, a maioria delas (56%) pertencentes Ă famĂlia Asteraceae. A maioria das espĂ©cies testadas pertencia a Asteraceae, mas outras 55 famĂlias foram tambĂ©m testadas, abrangendo um total de 77 gĂȘneros.Chloroform or dichloromethane extracts of 357 southern Brazilian plant species were tested for the presence of peroxides by thinlayer chromatography, using the spray reagent from Huber & Fröhlke. From the species tested, 71 (20%) showed positive results and most of them (56%) are Asteraceae species. The species tested were mainly from Asteraceae, but 55 more families were screened, in a total of 77 genera surveyed
