Enrichment of Nigella damascena Extract with Volatile Compounds using Supercritical Fluid Extraction

Popis výsledku v původním jazyce

beta-Elemene, germacrene A and damascenine were extracted from lady-in-a-mist (Nigella damascena L.) seeds with supercritical carbon dioxide at 10-30 MPa and 40-60 degrees C. The influence of supercritical fluid extraction (SFE) conditions on the yield and concentration of volatiles in the extract and the extraction kinetics were studied. The extraction yields and the apparent solubility of volatile compounds increased with increasing density of CO2. The highest total yield was obtained at 30 MPa and 40degrees C but the selectivity for volatiles was low under these conditions. With respect to both yield of volatiles and their concentration in extract, the best results were at 12 MPa and 40 degrees C, either with one separator or with additional separator maintained at 5 MPa and 25 degrees C. The yields of beta-elemene, germacrene A and damascenine reached 0.72, 3.31 and 3.65 mg g(-1) and their concentration in the extract was 2.62, 12.04 and 13.28 wt.%, respectively. Though the yields
