ABSTRACT

Microwave extraction of components from plant material has generated a great deal of scientific interest and promise in recent years. Traditional extraction procedures for active components are time and solvent demanding, thermally hazardous, and the extraction process limits the examination of several elements in plant material. Some of the appealing aspects of this new potential microwave assisted extraction (MAE) approach include high and quick extraction performance capability with minimal solvent consumption and protection afforded to thermolabile compounds. In the present study, a microwave-assisted extraction method was developed to extract natural phytochemicals from the stem bark of Codiaeum variegatum using various solvents such as Pet. ether, Chloroform, Ethyl acetate, Ethanol, and Water, and the percent yield and consistency of extracts, as well as extraction time, were compared to the extract prepared using the conventional method. Carbohydrates, Tannins, Saponins, Phenol, Alkaloids, Flavonoids and Steroids were found in Codiaeum variegatum extracts.
