Supercritical CO 2 extraction of nimbin from neem seeds – – a modelling study

Abstract

The extraction of nimbin from neem seeds using supercritical carbon dioxide is investigated in this paper. A model that accounts for intraparticle diffusion (De) and external mass transfer of nimbin (kf) is presented for the supercritical extraction process. Mass transfer is based on local equilibrium adsorption between solute (nimbin) and solid (neem solid… (More)
