The objective of this work was to perform a characterization chemical and phenolic profile 'Sauvignon Blanc' wines produced in the altitude region Santa Catarina State. study carried out with samples commercial wines, 2012 2013 vintages, selected from nine wineries. Two were taken each winery carry compounds, evaluating, triplicate: ethanol, residual sugar, pH, total acidity, color, polyphenols...

This study investigated the effect of deficit irrigation at three management allowable depletion levels (MAD) 25%, 50%, and 75% on phytochemicals, ascorbic acid, antioxidant activity, glucose, fructose, and fresh and dry mass in two green leafy lettuce cultivars (Lollo Bionda and Vera) at harvest. Genotype response was observed during deficit irrigation on fresh and dry mass at harvest. Vera re...

Background & Aim: The genus Echinacea (family Asteraceae), commonly known as purple coneflower, is an important medicinal plant that has been used for centuries, customarily as a treatment for the common cold, coughs, bronchitis, upper respiratory infections, and some inflammatory conditions . The present study was carried out to evaluate the effect of six different methods of ...

Phenolic acids existed in many agricultural products especially vegetables and considered as important natural antioxidants. Eleven phenolic commonly were chosen to assess the antioxidant activities using DPPH·, ·ABTS+, ·O2-, ·OH scavenging assays, well ferric reducing power ?-carotene bleaching assays. The results showed that caffeic protocatechuic acid with simple dihydroxylation structures h...

Evidences that higher natural antioxidant (NA) intake provides protection against cardiovascular disease (CVD) are contradictory. Oxidative-induced endothelial cells (ECs) injury is the key step in the onset and progression of CVD and for this reason the cellular responses resulting from NA interaction with ECs are actively investigated. This study was designed to investigate the direct impact ...

A method for the extraction of phenolic compounds from grape seeds and skins using microwave-assisted (MAE) was developed. Optimization effects parameters in terms results obtained response surface methodology. The studied were solvent (methanol, ethanol, acetone, water), percentage methanol water, quantity sample relation to volume (solid:liquid, 10–50 mg mL−1), power (100–500 W), magnetic sti...

Abstract One of the main purposes for which dandelions are cultivated is to derive phenolic acids from their processing. Phenolic acids, one useful compounds in dandelion, constitute important groups therapeutically significant bioactive traditional Chinese medicine. To carry out a relatively full evaluation dandelion quality, it was found advisable use multiple indices avoid conflict with sing...

About 600 species of Passiflora are described around the world, which 120 native to Brazil. In present work, phytochemical compounds were analyzed by high-performance liquid chromatography, and antioxidant activities (AOX) measured in pulp P. edulis cincinnata species. The presented a higher bioactive content AOX when compared cincinnata. Citric malic acids main organic found. principal compone...

BACKGROUND Studies of perennial peanut (Arachis glabrata Benth.) suggest its hay and haylage have greater levels of rumen undegraded protein (RUP) than other legume forages such as alfalfa (Medicago sativa L.). Greater RUP can result in more efficient nitrogen utilization by ruminant animals with positive economic and environmental effects. We sought to determine whether, like red clover (Trifo...
