Ethanol modified supercritical carbon dioxide extraction of antioxidant rich extract from Pereskia bleo

Supercritical fluid extraction (SFE) of Pereskia bleo leaves was carried out with systematic experimental study to screen and optimize the factors affecting yield and antioxidant activity. Initially, five factors were studied by Plackett–Burman study to screen the most influential factors. Consequen...
