Optimization of supercritical fluid extraction of phytosterol from roselle seeds with a central composite design model.

Recovery of phytosterol from roselle (Hibiscus sabdariffa L.) seeds via supercritical carbon dioxide extraction modified with ethanol was investigated at pressures of 200–400 bar, temperatures from 40 to 80 ◦C and at supercritical fluid flow rates from 10 to 20 ml/min. It was found that an entrainer...
