In the present work, the technical and economical analysis of extraction and isolation of indole alkaloids from Tabernaemontana catharinensis is presented. The extraction was carried out using supercritical CO 2 as solvent and ethanol as cosolvent (5%, v/v). The global yield isotherms were determined at 35 and 45°C for pressures of 150–350bar. The mass transfer rate for the constant extraction...
