Recovery and antioxidant activity of extracts from leptocarpha rivularis by supercritical carbon dioxide extraction
(2016)
We studied the effects of temperature (40, 50, and 60 degrees C) and pressure (9,12, and 15 MPa) on the recovery and antioxidant activity of the essential oil from Leptocarpha rivularis leaves by supercritical CO2 using a ...
Comparision of conventional and supercritical co2-extracted rosehip oil
(BRAZILIAN SOC CHEMICAL ENG, 2000)
Supercritical CO2 (SCO2) can be utilized to extract oils from a number of plant materials as a nontoxic alternative to hexane, and there is industrial interest in using SCO2 extraction to obtain high-quality oils for ...
Extraction of antioxidants from several berries pressing wastes using conventional and supercritical solvents
(SPRINGER, 2010)
The solid waste generated in industrial berry juice production was considered as a low cost raw material for the extraction of natural antioxidants. Berries contain phenolic compounds with high antioxidant potential, ...
