Uso analítico de tecidos e de extratos brutos vegetais como fonte enzimática

Abstract

This article describes the current status of several analytical methodologies using vegetal tissue and crude extracts as enzymatic source. In this divulgation paper the obtention of vegetal crude extract and/or tissue and selected enzymatic procedures are presented emphasizing its characteristics and peculiarities. Examples of many biosensors and/or flow injection procedures using vegetal tissues or crude extracts for the determination of many analytes, such as amines, ascorbic acid, ethanol, glutamate, hydrogen peroxide, oxalic acid, pectins, phenolic compounds and urea of biologic, environmental, food, pharmaceutical and industrial interests are also given and discussed.
