Solvent selection in microwave assisted extraction of castor oil

Castor oil has various uses in the field of cosmetics, plastics, manufacturing of biodiesel, lubricants and medicine. The use of microwave-Assisted extraction (MAE) of oils from plant materials has shown tremendous research interest and potential to overcome long extraction time and high solvent vol...
