Exploiting the Integrated Valorization of Eucalyptus globulus Leaves: Chemical ...
Oliveira, Cátia S. D.; Moreira, Patrícia; Cruz, Maria T.; Pereira, Cláudia M. F.; Silva, Artur M. S.; Santos, Sónia A. O.; Silvestre, Armando J. D.E. globulus leaves have been mainly exploited for essential oil recovery or for energy generation in industrial pulp mills, neglecting the abundance of valuable families of extractives, namely, triterpenic acids, that might open new ways for the integrated valorization of this biomass. Therefore, this study highlights the lipophilic characterization of E. globulus leaves before and after hydrodistillation, aimi...
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...
Characterization and Cytotoxicity Assessment of the Lipophilic Fractions of Dif...
Oliveira, Cátia S. D.; Moreira, Patrícia; Resende, Judite; Cruz, Maria T.; Pereira, Cláudia F.; Silva, Artur M. S.; Santos, Sónia A. O.Acacia dealbata biomass, either from forest exploitation or from the management of invasive species, can be a strategic topic, namely as a source of high-value compounds. In this sense, the present study aimed at the detailed characterization of the lipophilic components of different morphological parts of A. dealbata and the evaluation of their cytotoxicity in cells representative of different mammals' tissues...
Bioprospecting for lipophilic-like components of five Phaeophyta macroalgae fro...
Santos, Sónia A. O.; Oliveira, Cátia S. D.; Trindade, Stéphanie S.; Abreu, Maria H.; Rocha, Sílvia S. M.; Silvestre, Armando J. D.Lipophilic compounds present in dichloromethane extracts of five brown macroalgae from the Portuguese coast were analyzed by gas chromatography-mass spectrometry (GC-MS). Their dicarboxylic acids, long-chain aliphatic alcohols, and monoglyceride profile are reported for the first time. Additionally, other new compounds were also first reported: 24-methylene-cholesterol in Himanthalia elongata, Laminaria ochrole...
