The aim of the study was to investigate the effect of Ginkgo biloba extract 50 (GBE50), a well-known natural antioxidant, against immunity and antioxidant enzyme activities in ischemia reperfusion (IR) rats. Rats were then divided into six groups fed for 15 days with the same diet: three groups (IV,

OBJECTIVE To investigate and compare the antioxidant activities of salvianolic acid B (SalB) and Ginkgo biloba extract (EGb 761) in aqueous solution, rat microsomes and the cellular system. METHODS Superoxide anion (O2-.) was generated using xanthine/xanthine oxidase system and phenazine

Flavonoid glycosides are a significant group of compounds found in Ginkgo biloba leaves, but the long extraction procedures in existing methods are a challenging problem. In this work, a microwave-assisted extraction (MAE) method has been developed for extracting bioactive compounds from G. biloba.

Total phenolic content and antioxidant capacity (FRAP method) of Ginkgo biloba L. leaves collected from male and female trees were determined and compared. Different water and aqueous ethanolic (water/ethanol 80/20, V/V) extracts were prepared by varying the time of infusing, boiling and steeping in

Ginkgo biloba extract (EGb 761) has beneficial effects on cognitive functions in aging patients, and on various pathologies, including cardiovascular diseases. Although the extract is known to have antioxidant properties and improve membrane fluidity, the cellular mechanisms underlying these effects

Grape seed proanthocyanidins (GSPE) and ginkgo biloba extract (EGb761) are considered to have protective effects against several diseases. The cardiotoxicity of doxorubicin (DOX) has been reported to be associated with oxidative damage. This study was conducted to evaluate the cardioprotective

Proanthocyanidins have been shown to effectively protect ischemic neurons, but its mechanism remains poorly understood. Ginkgo proanthocyanidins (20, 40, 80 mg/kg) were intraperitoneally administered 1, 24, 48 and 72 hours before reperfusion. Results showed that ginkgo proanthocyanidins could

1. A total of 648 one-day-old broiler chicks were randomly allocated into six equal groups to investigate the effect of diet supplemented with fermented Ginkgo biloba leaves (FGBL) at different levels on nutrient utilisation, intestinal digestive function and antioxidant activity. 2. Broilers in the

The behaviour of the Ginkgo biloba L. seeds was studied during storage at 4 and 25 degrees C. When stored at 25 degrees C, all the seeds died in 6 months. Cold temperatures preserved seed tissue viability for 1 year but did not preserve their capability to germinate, since such capability decreased

An in vitro model using healthy human erythrocyte suspensions was used to compare the antioxidant effect of standardized Ginkgo biloba extract (EGb 761) with those of water-soluble (ascorbic acid, glutathione and uric acid) and lipid-soluble (alpha-tocopherol and retinol acetate) antioxidants. Lipid

The aim of this work was to compare in the rat the cardioprotective efficacy and the total plasma antioxidant activity of a standardised Ginkgo biloba L. extract (GB) as such (300 mg/kg/day) or complexed with phosphatidylcholine (GB-PC; 1:2 w/w), after a 5 days oral administration. At the end of the

Several investigations have recently shown that the retina is very sensitive to oxygenated free radicals (O2-, OH.) at the origin of the membrane phospholipids peroxidation. Peroxy radical (ROO.) release is responsible for the induction of electrophysiological disturbances leading to retinopathy

Silver nanoparticles (AgNPs) are noble metal nanoparticles, due to their good physicochemical properties, which have been exploited in biological applications. Nanotechnological applications advance very quickly while few literatures assessed the effects of natural products on the risks of

Diabetic retinopathy is a microvascular complication of diabetes and has complex and multifactorial pathogenesis. Cascade of biochemical changes characteristic to other diabetes vascular complications leads to structural changes of retinal capillaries some of which are unique. As a result of all

The desired mix of alpha-linolenic acid (ALA)-enriched structured lipid (SL) and physically blended lipid (PB) was prepared from grape seed oil and perilla oil at a weight ratio of 3:1. The major triacylglycerol species (LnLnL) in PB was drastically increased after interesterification (SL), from
