Supercritical CO2 oil extraction from Bauhinia forficata link subsp. pruinosa leaves: Composition, antioxidant activity and mathematical modeling

The subspecies B. forficata subsp. pruinosa is practically unexplored scientifically. Thus, the aim of this study was to evaluate a supercritical fluid extraction method and to compare it with the conventional Soxhlet method. The supercritical fluid extraction was performed with CO2, at temperatures of 40–60 °C and pressures of 18–22 MPa, while the Soxhlet method was conducted using ethanol, ethyl acetate and n-hexane as solvents. The extract...
