An integrated green process for the extraction of triterpenic acids fromEucalyp...
Oliveira, Cátia S. D.; Moreira, Patrícia; Cruz, Maria T.; Pereira, Cláudia M. F.; Gaspar, Alexandre; Neto, Carlos Pascoal; Pinto, Paula C. R. O.In this study the viability of the integrated exploitation of E. globulus leaf essential oil and triterpenic acids was evaluated through the development of a novel extraction process that can be implemented sequentially in a biorefinery context. Thus, essential oil (EO) collected by hydrodistillation was used for the first time as a bio-based solvent to recover triterpenic acids (TTAs) from the residue resultin...
Quercus suber and Betula pendula outer barks as renewable sources of oleochemic...
Pinto, Paula C. R. O.; Sousa, Andreia F.; Silvestre, Armando J. D.; Neto, Carlos Pascoal; Gandini, Alessandro; Eckerman, Christer; Holmbom, BjarneA comparative study on the chemical composition of oak cork (Quercus suber L.) and corresponding industrial residues and birch (Betula pendula L.) outer bark is reported. Cork oak samples have lower extractives contents (6-9%) and higher contents of carbohydrates and lignin (23-27 and 33-38%, respectively) than those found for birch outer bark (40, 6 and 9%, respectively); suberin contents accounted for around ...
