The active ingredients of 'golden root' of Scutellaria baicalensis GEORGI (Huang-Qin), a valuable traditional Chinese medicine, are polyhydroxyflavonoids, namely baicalein, oroxylin A and wogonin. With the objective of overcoming their poor solubility and to investigate their structure and activity relationships, baicaleinyl 7-O-sulfate was prepared, and extensive comparative antioxidative and ...
High doses of synthetic antioxidative vitamins: A, E, C and β-carotene are often used on long-term basis in numerous preventive and therapeutic medical applications. Instead of expected health effects, the use of those vitamins may however lead to cases of hypervitaminosis and even to intoxication. The article points out main principles of safety which are to be observed during supplementation ...
BACKGROUND Tea seed oil is a high quality edible oil, yet lacking sufficient scientific evidences to support the nutritional and medical purposes. We identified major and minor components in Camellia tenuifolia seed oil and investigated the antioxidative activity and its underlying mechanisms in Caenorhabditis elegans. PRINCIPAL FINDINGS The results showed that the major constitutes in C. ten...
The neuroprotective and antioxidative effects of germinated brown rice (GBR), brown rice (BR) and commercially available γ-aminobutyric acid (GABA) against cell death induced by hydrogen peroxide (H(2)O(2)) in human neuroblastoma SH-SY5Y cells have been investigated. Results show that GBR suppressed H(2)O(2)-mediated cytotoxicity and induced G0/G1 phase cell cycle arrest in SH-SY5Y cells. Moreo...
Study of antioxidative properties and Maillard reaction (MR) products in ginger cakes enriched with rutin was conducted. The cakes were formulated on rye flour substituted by 30% (w/w) of flour from husked buckwheat or flour from roasted buckwheat groats. Enrichment of rye-buckwheat ginger cakes with rutin improved their antioxidative properties, showed protective effect on lysine blockage and ...
Oxidative stress has been implicated in pathophysiology of aging and age-associated disease. Antioxidative medicine has become a practice for prevention of atherosclerosis. However, limited success in preventing cardiovascular disease (CVD) in individuals with atherosclerosis using general antioxidants has prompted us to develop a novel antioxidative strategy to prevent atherosclerosis. Reducin...
Role of salicylic acid pre-treatment on the acclimation of tomato plants to salt- and osmotic stress
The alleviation of oxidative damage and increased resistance to salt stress and to non-ionic osmotic stress induced by 100 mM NaCl or 100 mOsm polyethylene glycol (PEG) treatments, respectively, often correlate with a more efficient antioxidative defence systems and detoxification mechanisms. Pre-treatment of plants with salicylic acid (SA) enhanced antioxidant enzyme activities in concentratio...
Diosgenin (a steroidal saponin of yam) has long been used as a raw material for the industrial production of steroid drugs, and reported to have a hypocholesterolemic effect by suppressing cholesterol absorption and increasing cholesterol secretion. Oxidative stress has been suggested as a main risk factor in the development of atherosclerosis. The aim of this study is to investigate the possib...
AIM To estimate the impact of high fat diet and estrogen deficiency on the oxidative and antioxidative status in the liver of the ovariectomized rats, as well as the ameliorating effect of physical activity or consumption of functional food containing bioactive compounds with antioxidative properties on oxidative damage in the rat liver. METHODS The study was conducted from November 2012 to A...
Traumatic brain injury (TBI) leads to a deleterious and multifactorial secondary inflammatory response in the brain. Oxidative stress from the inflammation likely contributes to the brain damage although it is unclear to which extent. A largely unexplored approach is to consider phenotypic regulation of oxidative stress levels. Genetic polymorphism influences inflammation in the central nervous...
