Strawberries are highly appreciated for their taste, nutritional value and antioxidant compounds, mainly phenolics. Fruit antioxidants derive from achenes and flesh, but achene contribution to the total fruit antioxidant capacity and to the bioaccessibility after intake is still unknown. In this work, the content of total phenolic compounds, flavonoids, anthocyanins and antioxidant capacity (TE...

reactive oxygen species (ros) generation, induced by the cryopreservation process, can be responsible for mammalian sperm damage. curcumin is known as an effective antioxidant against oxidative stress. the aim of this study was to evaluate the effects of curcumin on sperm count, motility and viability, semen total antioxidant capacity and dna integrity of rat spermatozoa during semen freeze-tha...

PURPOSE Because varicocele is seen often in infertile men and oxidative stress has been implicated in sperm dysfunction, we assessed spermatozoal reactive oxygen species and seminal total antioxidant capacity in men with and without varicocele. MATERIALS AND METHODS Levels of reactive oxygen species and total antioxidant capacity were measured in the semen of 21 infertile men with varicocele,...

This study was conducted to assess the effect of ginger supplementation on malondialdehyde (MDA) level, as an oxidative stress marker, and total antioxidant capacity (TAC) in broiler chicks. Two hundred male 1-day-old chicks were assigned randomly to four dietary treatments (basal diet as control group and basal diet containing 2.5, 5.0 and 7.5 g/kg ginger, respectively), with five replicates a...

Total phenol contents of O.vulgare were found between 54.23 mg GAE/g (U4) and 124.55 mg GAE/g (U2), respectively. While total phenol contents of O.minutiflorum change between 49.50 mg GAE/g (U5) and 126.92 mg GAE/g (S3), total flavonol contents were found between 623.87 mg RE/g (U5) and 854.53 mg RE/g (U2). Antioxidant capacity ranged from 42.31 mg AAE/g (U5) to 103.04 mg AAE/g (S3). Total ...

The aim of this study was to compare the contents of the main biochemical compounds and the antioxidant capacity of five Spanish olive oils by four different antioxidant tests and to find out the most valuable oil for disease preventing diets. Fatty acids, sterols and individual antioxidant compounds in Arbequina, Hojiblanca, Extra Virgin, Picual and Lampante Spanish olive oils were determined....

costus speciosus (koen) j.e. sm. plant and its extracts are used for treatment of fever, snake bites, jaundice, and as a purgative, astringent and antibacterial agent. in the present study, an attempt has been made to evaluate in vitro antioxidant activity of different extracts of this plant by dpph radical scavenging activity, total antioxidant capacity, nitric oxide scavenging activity, ion c...

Th e aim of this study was to determine the chemical composition and antioxidants capacity of three plum cultivars, namely ‘Top’, ‘Elena’ and ‘Bistrica’. Fruits were harvested and following parameters were determined: dry matter, total acids (TA), total soluble solids (TSS), pH, vitamin C, total phenols, nonfl avonoids and antioxidant capacity. Diff erences between cultivars for most of the che...

Introduction: Toxic effects of pesticides are commonly associated with reactive oxygen species damage and pentoxifylline a phosphodiesterase inhibitor is a drug well known for antioxidant properties. The purpose of this study was to evaluate the oxidative damages following a subacute exposure to malathion, an organophosphorus insecticide and pentoxifylline's ability to counteract these effect...
