Microwave assisted extraction of soy isoflavones

Analytica Chimica Acta, 2007
A fast and reliable analytical method using microwave assisted extraction has been developed. Several extraction solvents (methanol (MeOH) and ethanol (EtOH), 30-70% in water and water), temperatures (50-150 degrees C), extraction solvent volume, as well as the sample size (1.0-0.1g) and extraction time (5-30 min) were studied for the optimization of ...

Ultrasound-assisted extraction of soy isoflavones

Journal of Chromatography A, 2003
Efficiency in extracting four isoflavone derivatives (daidzin, glycitin, genistin and malonyl genistin) from freeze-dried ground soybeans was compared for mix-stirring extraction and ultrasound-assisted extraction, using different solvents and extraction temperatures with both.
