Supercritical Extraction of Scopoletin from Helichrysum italicum (Roth) G. Don Flowers

ConclusionThe extraction conditions, especially pressure, exhibited significant influence on the extraction yield as well as the yield of extracted scopoletin and antioxidant activity of extracts. Copyright © 2016 John Wiley & Sons, Ltd.

Supercritical CO2 extraction of H. italicum flowers at different values of pressure and temperature was performed in order to optimize the extraction process using response surface methodology in terms of getting higher extraction yield and yield of scopoletin. The greatest extraction yield and the highest yield of scopoletin were obtained under extraction conditions of 20 MPa and 40°C. Extracts have also proven to possess antioxidant activity influenced by both temperature and pressure applied within the investigated parameters.
