Supercritical carbon dioxide extraction of Trigonella foenum-graecum L. seeds: Process optimization using response surface methodology

- Extraction of diosgenin by supercritical extraction on a wide range of condition parameters was examined.
- Procedure of diosgenin isolation from fenugreek including pretreatment of plant and SCE was applied and described.
- Influence of pressure, temperature and amount of CO2 on diosgenin extraction was determined.
- Optimization of supercritical extraction of diosgenin was examined.
