Determinação da atividade antioxidante e antimicrobiana de orquídeas

Abstract

The largest group of flowers is considered the Orchidaceae family, which grows mainly in tropical regions. Although few, there are studies that prove its antioxidant activities, being molecules capable of delaying or preventing oxidation, acting on food or biological systems. The objective of this work was to determine the antioxidant and antimicrobial activity in orchids. The antioxidant activity was determined by DPPH, FRAP, ABTS, phenolic compounds and flavonoids. The antimicrobial activity was determined by the disc diffusion test method and minimum inhibitory concentration. Through this work, it was concluded that there is antioxidant and antimicrobial activity for the studied orchids.
