Determination of phenolic composition and antioxidant activity in fruits, rhizomes and leaves of the white strawberry (Fragaria chiloensis spp. chiloensis form chiloensis) using HPLC-DAD-ESI-MS and free radical quenching techniques
(Academic Press Inc Elsevier Science, 2010-09)
A comparative analysis of methanol extracts from fruits, rhizomes and leaves of the Chilean white strawberry (Fragaria chiloensis spp. chiloensis var chiloensis) was performed by means of reversed phase high-performance ...
A natural deep eutectic solvent as a novel dispersive solvent in dispersive liquid-liquid microextraction based on solidification of floating organic droplet for the determination of pesticide residues
(Springer Heidelberg, 2021-08)
Current trends in analytical chemistry encourage the use of innocuous solvents to develop modern methods aligned with green chemistry. In this sense, natural deep eutectic solvents (NADESs) have emerged as a novel generation ...
Multi-phytochemical determination of polar and non-polar garlic bioactive compounds in different food and nutraceutical preparations
(Elsevier, 2021-02)
Amongst functional foods, garlic and its by-products stand out given their rich phytochemical profile. A comprehensive analytical approach becomes necessary to fully address garlic preparations health-promoting activities, ...
Reliable and simple analytical methods for determination of citrulline and metabolically related amino acids by liquid chromatography after derivatization: comparison between monolithic and core–shell columns
(Royal Society of Chemistry, 2014-08)
We describe the development of a high-performance liquid chromatography (HPLC) method for the determination of citrulline and other amino acids relevant to intestinal diseases. The amino acids were derivatized with ...
Physiological stress in captive Greater rheas (Rhea americana): Highly sensitive plasma corticosterone response to an ACTH challenge
(Academic Press Inc Elsevier Science, 2009-12)
Up to the present no studies have been conducted either on baseline concentrations of adrenal hormones or on hormonal responses to stress in Greater rhea (Rhea americana) and most ratite species. The aims of this work were ...
Wheat storage proteins: changes on the glutenins after wheat infection with different isolates of Fusarium graminearum
(Viguera Editores, 2019-06)
Wheat gluten proteins are decisive for the industrial properties of flour, so alterations resulting from grain infection with Fusarium graminearum produce changes in the glutenin content that affect the baking properties. ...
Integrated SPE-Self assembled MEPS platform for ultrasensitive determination of mononitrophenols in water: Experimental, computational and applicability studies
(Elsevier Science, 2020-05)
Integrated analytical approaches can be used to determine the trace concentrations of analytes in water matrices. Here we designed and compared two novel and facile, integrated polysaccharide adsorbent SPE-Self assembled ...
