The aim of this study was to evaluate the effect of the addition of organic compost in combination with the inorganic nitrogen fertigation on growth, phytochemical accumulation, and antioxidant activity of spinach (Spinacia oleracea L. cv. Manatee). Soil blocked spinach seedlings (six
Oxidized low-density lipoprotein (LDL) is considered a risk factor in atherosclerosis, and polyphenols are the potential agents to inhibit the oxidation of LDL. We determined the polyphenol contents and the antioxidant activities of commonly consumed vegetables in Vietnam and assessed the quantity
High temperature is a major environmental factor affecting plant growth. Heat shock proteins (Hsps) are molecular chaperones that play important roles in improving plant thermotolerance during heat stress. Spinach (Spinacia oleracea) is very sensitive to high temperature; however, the specific
The significance of plant growth-promoting rhizobacteria (PGPR) mediated increase in antioxidant potential in vegetables is yet unknown. The plant growth-promoting bacterium Bacillus lentimorbus NRRL B-30488 (B-30488) mediated induction of dietary antioxidant in vegetables ( Trigonella
The plants of Spinacia oleracea L. grown on contaminated soil (CS) and different amendments of tannery sludge (TS) have shown high accumulation of metals in its edible part. The accumulation of toxic metal (Cr) in the leaves of the plants grown on CS was recorded as 40.67 microgg(-1)dw. However, the
Of late, more attention has been paid to the role of natural antioxidants, especially phenolic compounds, which may act both by reducing the content of toxic compounds in foods and by supplying the human body with exogenous antioxidants. The total phenolic contents and the total antioxidant
omega-3 fatty acids, alpha-tocopherol, ascorbic acid, beta-carotene and glutathione determined in leaves of purslane (Portulaca oleracea), grown in both a controlled growth chamber and in the wild, were compared in composition to spinach. Leaves from both samples of purslane contained higher amounts
BACKGROUND
Consumers have become more interested in beneficial effects of vegetables, fruits, and tea to protect their health.
OBJECTIVE
The antioxidant potential and anticholinesterase activity of eleven edible plants were investigated.
METHODS
The dichloromethane, ethanol and water extracts
OBJECTIVE
To examine plasma total antioxidant capacity (TAOC) in a Chinese population with a lower incidence of cardiovascular disease compared with Caucasian populations, in relation to dietary intake, age, sex, and the presence of cardiovascular diseases.
METHODS
As part of a randomized
The antioxidant effect of reduced plastoquinone was studied in chloroplast membranes. Isolated spinach thylakoid membranes were subjected to strong illumination followed by analysis of pigment bleaching and lipid peroxidation. The plastoquinone pool was kept in the reduced or oxidized state during
Black shank caused by Phytophthora nicotianae is one of the most devastating diseases in tobacco production. In this study, we characterized a novel cytochromic resistance gene, SoCYP85A1, from spinach, which was upregulated in response to P. nicotianae infection. Overexpression
Essential oils are natural antimicrobials that have the potential to provide a safer alternative to synthetic antimicrobials currently used in the food industry. Therefore, the aim of this study was to evaluate the antimicrobial and antioxidant activities of essential oils from white wormwood,
Natural antioxidants have received increased attention owing to their safe use without side effects; however, their application has been limited because of lower antioxidant activity and stability during digestion when compared with those of synthetic antioxidants. Although research is Release of bioactive compounds from food matrices is regarded as the first step towards their human bioavailability. The objective of this work was the implementation of an affordable and robust flow-through device for expedient dynamic leaching experiments aiming at the assessment of readily
To evaluate the physiological importance of thylakoid membrane-bound ascorbate peroxidase (tAPX) in the active oxygen species-scavenging system of chloroplasts, the level of tAPX in tobacco plants was altered by expression of the tAPX cDNA in both sense and antisense orientation. The tobacco plants
