sea algae are widely consumed in the world. there are several seaweeds including brown algae which are authorized for human consumption. these plants contain important phytochemical constituents and have various potential biological activities. the present study investigated the presence of phytochemical constituents and total phenolic quantity of the seaweeds sargassum angustifolium , sargassu...

The aim of this study was to determine the in vitro antioxidant activity, free radical scavenging property and the beneficial effects of extracts of various parts of Syzygium guineense in reducing oxidative stress damage in the liver. The effects of extracts on free radicals were determined on radicals DPPH, ABTS, NO and OH followed by the antioxidant properties using Ferric Reducing Antioxidan...

this study was designed to examine the in vitro antioxidant activities and total phenolic contents of the methanolic extracts from male inflorescence of salix aegyptiaca l. grown in iran. the methanolic extract (me) and its three fractions including water (wf), butanol (bf) and chloroform (cf) were prepared and then their antioxidant activities, as well as total phenolic contents, were evaluate...

The present controlled-training double-blind study (supplemented (S) group, n 7; placebo (P) group, n 10) was designed to investigate whether an antioxidant mixture (Se 150 microg, retinyl acetate mg, ascorbic acid 120 mg, alpha-tocopheryl succinate 20 mg) would allow overloaded triathletes to avoid adaptation failure in the antioxidant system [corrected]. Dietary intakes were recorded. The sup...

background: the lamiaceae family has been tried to ameliorate symptoms of stomachache and dysmenorrheal in traditional medicine. the extracts and essential oils obtained from these plants have recently attracted much scientific attention. the essential oils of some plants belonging to this family have also been used in food preservation. methods: this study employed pharmaco-diagnostic methods ...

a new cyclic diarylheptanoid namely alnuheptanoid b (3), along with four known cyclic diarylheptanoids: myricanone (1), (+)-s-myricanol (2), myricanone 5-o--d-glucopyranoside (4), and (+)-s-myricanol 5-o--d-glucopyranoside (5) were isolated from the etoac fraction of alnus japonica steud (family: betulaceae) stem bark. their structures were established by different spectroscopic analyses, as ...

OBJECTIVE To evaluate and compare standard sperm parameters, lipid peroxidation of sperm plasma membranes, antioxidant capacity of seminal plasma, and sperm chromatin integrity in ejaculates from men whose partners have a history of recurrent pregnancy loss and from a control group of men with recent fertility. DESIGN Descriptive study. SETTING Reproduction Program, University of Antioquia,...

Aim of the study: To evaluate the antioxidant property of Smilax zeylanica L. using CCl4 hepatotoxicity in rats. Materials and methods: Hepatotoxicity was induced in Wistar albino rats by administration of CCl4 (0.5ml/kg/day p.o. for 7days). Methanol extract of S. zeylanica roots and rhizomes (SZRM) was administered to the experimental animals at doses 200,400 and 600 mg/kg/day, p.o. for 7 days...

objective: antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions. materials and methods: in this research the antioxidant potential of the fresh fruits of 4 cultivars (a to d) of malus domestica (m. domestica) cultivated in the kashan, qamsar area was evaluated. the antioxidant activity of the samples were evaluated using two complementary antioxidant...

Objective(s): The objectives of the current study were to evaluate the effects of hepatic ‎ischemia/reperfusion (IR) injury on the activity of antioxidant enzymes, biochemical factors, and ‎histopathological changes in rat kidney, and to investigate the effect of crocin on IR-‎related changes. Materials and Methods: Thirty-two male Wistar rats were randomly allocated into four groups (n=8). The...
