Besides giving colour to plants, anthocyanins also have antioxidant and anti-hyperglycemic properties; hence, they are used as therapeutic source for many treatments of diabetes, coronary heart disease and cancer. Many anthocyanin extraction methods such as conventional acidified water (CAW), ultrasound, microwave pre-treatment, supercritical fluid extraction and pulsed electric field (PEF) have been used.

Oil was extracted from moringa (PKM-1) seed kernel by using supercritical fluid (SCCO2) extraction process. Supercritical fluid pressures of 100, 150 and 200 bar and temperatures of 40, 50 and 60 °C were considered for SC-CO2 extraction process. Maximum extraction yield of 37.76 g/100g and extraction efficiency of 98.43% were obtained at supercritical fluid pressure of 200 bar and temperature of 40 °C.

The Supercritical Fluid extraction is also considered as a novel technology for extracting soluble products into a fluid from a wide range of materials using supercritical conditions of solvents. Bioactive compounds are secondary metabolites produced from a broad diversity of structures and functionalities. In the present article the potential bioresources mainly from agriculture and allied sectors have been reviewed which constitutes excellent pools for bioactive and nutraceutical compounds.

The purpose of this work is to provide a complete study of the influence of operational parameters of the supercritical carbon dioxide assisted extraction (SC CO2E) on yield of wedelolactone from Wedelia calendulacea Less., and to find an optimal combination of factors that maximize the wedelolactone yield. In order to determine the optimal combination of the four factors viz. operating pressure, temperature, modifier concentration and extraction time, a Taguchi experimental design approach was used: four variables (three levels) in L9 orthogonal array.

Shiitake mushroom contains several therapeutic actions such as antioxidant and antimicrobial properties, carried by the diversity of its components. In the present work, extracts from shiitake mushroom were obtained using different extraction techniques: high-pressure operations and low-pressure methods. The high-pressure technique was applied to obtain shiitake extracts using pure CO2 and CO2 with co-solvent in pressures up to 30 MPa.
