Phenolic diterpenes of rosemary andcarotenoids of spinach were target compounds due their recognized biological activities. Two different extraction techniques were applied, namely pressurized liquid extraction using hexane at two different temperatures (100 and 150◦C) and supercritical fluid extraction with pure carbon dioxide at 40◦C andtwo different pressures (20 and 30 MPa). For each extraction technique and conditions three differentraw materials were employed: spinach leaves, rosemary leaves and the mixture 50:50 of spinach androsemary leaves.The antioxidant activity of the samples produced was evaluated with the ABTS assay and showed tobe enhanced when the species are simultaneously extracted, with antioxidant values around 20% higherthan the values corresponding to mixing the extracts obtained by separate. A possible synergic effect between carotenoids and phenolic diterpenes was studied, although no specific synergic activity couldbe observed. However, the enhanced antioxidant activity could be attributed to a definite increase ofthe concentration of carnosic acid, which was observed in the samples produced by the simultaneous extractionThis work has been supported by project INNSAMED IPT-300000-2010-34 (subprogram INNPACTO) from Ministry of Scienceand Innovation (Spain) and project ALIBIRD-S2009/AGR-1469 from Autonomous Community of MadridElsevier B.VDepartamento de Química Física AplicadaFacultad de Ciencias20132013-10-31research articlehttp://purl.org/coar/resource_type/c_2df8fbb1AMhttp://purl.org/coar/version/c_ab4af688f83e57aainfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10486/662237https://dx.doi.org/10.1016/j.supflu.2013.07.004reponame:Biblos-e Archivo.
