Martins, Vitor Manuel Ramalheira; Ferreira, Isabel V.; Cruz, Maria T.; Batista, Maria T.; Coimbra, Manuel A.In Trás-os-Montes region (Portugal), the small shrub (Pterospartum tridentatum), the narrow-leafed ash (Fraxinus angustifolia), and the apple mint (Mentha suaveolens) are vegetable species used in the preparation of infusions for medicinal purposes, such as protection against diabetes, hypertension, high levels of cholesterol and uric acid [1]. These infusions contain several types of polysaccharides, such as p...
Relevant principal component analysis applied to the characterisation of Portug...
Martins, Rui C.; Lopes, Victor V.; Valentão, Patrícia; Carvalho, João C. M. F.; Isabel, Paulo; Amaral, Maria T.; Batista, Maria T.; Andrade, Paula B.The main purpose of this study was the characterisation of ‘Serra da Lousã’ heather honey by using novel statistical methodology, relevant principal component analysis, in order to assess the correlations between production year, locality and composition. Herein, we also report its chemical composition in terms of sugars, glycerol and ethanol, and physicochemical parameters. Sugars profiles from ‘Serra da Lousã...
Fractioned High Pressure Extraction of Anthocyanins from Elderberry ( Sambucus ...
Seabra, Inês J.; Braga, Mara E. M.; Batista, Maria T. P.; Sousa, Hermínio C. deFractionated high pressure extractions from dry and in natura elderberry pomace were performed in order to obtain anthocyanin rich extracts. Experiments were carried out using CO2 supercritical fluid extraction followed by enhanced solvent extraction (ESE) with CO2/EtOH–H2O mixtures (1–100%, v/v), to obtain anthocyanin rich fractions in the second step, at 313 K and ~20 MPa. Higher extract yields, anthocyanin c...
