چکیده انگلیسی
Supercritical fluid was used to extract berberine from rhizome of Coptis chinensis Franch. The recovery of berberine was compared with various modifiers, i.e. methanol and 95% ethanol with and without surfactant Tween 80, and 1,2-propanediol. The results show that the yield obtained after 3 h extraction with 1,2-propanediol-modified supercritical carbon dioxide was the highest (from 6.91%, w/w at 200 bar to 7.53%, w/w at 500 bar), while that obtained with 95% ethanol modified-supercritical carbon dioxide was the lowest (from 0.15%, w/w at 300 bar to 0.19%, w/w at 600 bar). The recovery of berberine was not improved by adding 5% Tween 80 in supercritical fluid.
