Potential use of the ATR-FTIR spectroscopy as an almond cultivar recognition to...
Lamas, Sandra; Rodrigues, Nuno; Santamaria-Echart, Arantzazu; Palu, Igor; Manhique, Jocyla; Herrero, Baudilio; Lopéz-Cortés, IsabelThree almond cultivars (Lauranne, Marinada, and Vairo) were studied, considering morphological parameters that showed statistical cultivar-dependence but not enabled accurate cultivar recognition. Alternatively, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) was applied to whole endocarp, kernel, and ground almonds. Both transmittance spectra and respective derivatives (3400–280...
Identification of the geographical origin of Spanish beech nuts, Fagus sylvatic...
Lamas, Sandra; Rodrigues, Nuno; Herrero, Baudilio; Casal, Susana; Cruz, Rebeca; Pereira, José Alberto; Peres, António M.In general, dry nuts, such as hazelnuts, almonds. chestnuts and walnuts, composition has been investigated and are well characterized. Nevertheless, other less unknown nuts, such as beech nuts have little information. Beech nuts proceed from the Fagus sylvatica L. tree, which is prevalent in central and southem Europe, and is commonly used for oil extraction. A study carried out by Obranovic et al. found that t...

Lamas, Sandra; Rodrigues, Nuno; Herrero, Baudilio; Casal, Susana; Cruz, Rebeca; Pereira, José Alberto; Peres, António M.In general, dry nuts, such as hazelnuts, almonds, chestnuts and walnuts, composition has been investigated and are well characterized. Nevertheless, other less unknown nuts, such as beech nuts have little information. Beech nuts proceed from the Fagus sylvatica L. tree, which is prevalent in central and southern Europe, and is commonly used for oil extraction. A study carried out by Obranovic et al.1 found that...
By-product of Lavandula latifolia essential oil distillation as source of antio...
Méndez-Tovar, Inés; Herrero, Baudilio; Pérez-Magariño, Silvia; Pereira, J.A.; Asensio-S.-Manzanera, M. CarmenThe objective of this work was to evaluate the antioxidant properties of Lavandula latifolia waste obtained after essential oil distillation. Samples of 12 wild populations of the Lavandula genus collected between 2009 and 2010 were hydrodistilled and their by-products were analyzed using the FolineCiocalteu, free radical scavenging activity (2,2-diphenyl-1- picrylhydrazyl), and the ferric reducing antioxidant ...
Antioxidant activity of twenty wild Spanish Thymus mastichina L. populations an...
Delgado, Teresa; Marinero, Pilar; Asensio-S.-Manzanera, M. Carmen; Asensio, Carmen; Herrero, Baudilio; Pereira, J.A.; Ramalhosa, ElsaThe antioxidant activity and chemical composition of essential oils and methanolic extracts of twenty Spanish Thymus mastichina L. populations were studied. Both essential oils and methanolic extracts possessed antioxidant properties. However, the total phenol contents of the methanolic extracts varied between 2.90 and 9.15mg GAE/g extract and the EC 25 values of DPPH free radical scavenging activity between 0....

Delgado, Teresa; Pilar, Marinero; Asensio-S.-Manzanera, M. Carmen; Asensio, Carmen; Herrero, Baudilio; Pereira, J.A.; Ramalhosa, ElsaO tomilho (Thymus sp.) e geralmente usado como especiaria e/ou erva medicinal com diversas propriedades farmacológicas, tais como anti-espasmódicas, anti-sépticas, anti-tússicas, expectorantes, entre outras. Os óleos essenciais extraídos do tomilho tem também encontrado uso na dieta humana, uma vez que tem sido demonstrada actividade antimicrobiana face a microrganismos patogénicos, tais como Staphylococcus aur...
