Extraction of β-sitosterol from Swietenia mahagoni seeds by using supercritical carbon dioxide (SC-CO2) extraction

β-Sitosterol: Supercritical Carbon Dioxide Extraction from Sea Buckthorn (Hippophae rhamnoides L.) Seeds

Supercritical fluid extraction represents an efficient and environmentally friendly technique for isolation of phytosterols from different plant sources. Sea buckthorn (Hippophae rhamnoides L.) seeds were extracted with supercritical carbon dioxide at pressures ranging from 15-60 MPa and temperatures of 40-80 degrees C. Oil and β-sitosterol yields were measured in the extraction course and comp...

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Inhibitory Effects of Swietenia Mahagoni Seeds Extract on Α-Glucosidase and Α-amylase

This study analyzed the inhibition activity of Swietenia mahagoni seeds extract on α-glucosidase and α-amylase enzymes inhibition assays.  Swietenia mahagoni seeds were extracted by using Supercritical Carbon Dioxide (SC-CO2) extraction at pressures of 20- 30 MPa and temperatures of 40- 60°C.  The oil yields obtained were analyzed with α- glucosidase and α- amylase enzymes inhibition assays.  A...

Supercritical Carbon Dioxide Extraction of Bioactive Compounds from Feijoa (Feijoa sellowiana) Leaves

Background and Objectives: Supercritical fluid extraction (SFE) technique has been studied for extraction of bioactive compounds from Feijoa sellowiana leaves. Results were compared with those obtained from conventional ethanolic extraction (CE). Materials and Methods: Results: The best supercritical carbon dioxide (SC-CO2) extraction conditions was determined as 250 bar of pressure, 50 &deg...

SUPERCRITICAL CARBON DIOXIDE EXTRACTION OF PIGMENTS FROM Bixa orellana SEEDS (EXPERIMENTS AND MODELING)

Supercritical CO2 extraction of the pigments from Bixa orellana seeds was carried out in a flow apparatus at a pressure of 200 bar and a temperature of 40 oC at two fluid flow rates (0.67g/min and 1.12g/min). The efficiency of the extraction was low (only about 1% of the pigment was extracted). The increase in flow rate led to a decrease in pigment recovery. A large increase in recovery (from 1...
