antioxidants are compounds which can prevent biological and chemical substances from oxidative damage by reactive oxygen species. flavonoids are the most important class of polyphenolic compounds that because of their antioxidant characters possess biological activities and pharmacological effects. chrysin-6-c-fucopyranoside and chrysin-3-malonyl-6-c-fucopyranoside are mono c-glycosyl derivativ...

This study aimed to investigate the effects of flavonoid glycoside on mitochondrial dysfunction and inflammatory oxidative stress in macular degeneration. Sixty specific-pathogen-free male Bagg Albino mice were randomly divided into control, model glycoside. Human retinal pigment epithelium cells ARPE-19 cultured treated with dimethyl sulfoxide, sodium iodate respectively. Fundus fluorescein an...

Following our interest in new diterpene glycosides with better taste profiles than that of Rebaudioside M, we have recently isolated and characterized Rebaudioside IX-a novel steviol glycoside-from a commercially-supplied extract of Stevia rebaudiana Bertoni. This molecule contains a hexasaccharide group attached at C-13 of the central diterpene core, and contains three additional glucose units...

to its glycoside (arachidoside) content. On the basis of in creased excretion of phenols in the group of rats fed arachi doside, and of an increased iodine content in the phenolic fraction of the urine as compared with the control, it was sug gested that this glycoside acted as an antithyroid compound by forming molecular compounds with elemental iodine in the gland. Confirmatory evidence for t...

tribulus terrestris l. var. orientalis (kerner) g. beck is widely used in the traditional medicine of many countries. several flavonoides are identified from the plant material. aerial parts which collected from northeast of iran are used in this study. three flavonoid glycosides were isolated and characterized. the flovonoids were found to be based on quercetin and kaempferol. flavonoid glycos...

Group A streptococcus (Streptococcus pyogenes) is the causative agent of severe invasive infections such as necrotizing fasciitis (the so-called 'flesh eating disease') and toxic-shock syndrome. Spy1600, a glycoside hydrolase from family 84 of the large superfamily of glycoside hydrolases, has been proposed to be a virulence factor. In the present study we show that Spy1600 has no activity towa...

A total of 10 steroidal glycosides, together with three new spirostanol glycosides (6-8), a new furostanol glycoside (9), and a new cholestane glycoside (10), were isolated from the rhizomes of Clintonia udensis (Liliaceae). The structures of the new compounds were determined on the basis of extensive spectroscopic analyses, including 2-D nuclear magnetic resonance (NMR) data, and of hydrolytic...

Background This study was designed to explore the correlation of connective tissue growth factor (CTGF), heme oxygenase (HO-1), neurotrophic factors (NT-3) with type 2 diabetic peripheral neuropathy, as well as the changes after immune cytokine alone and combined with cattleencephalon glycoside and ignotin treatment. Methods Seventy-six patients with type 2 diabetes and peripheral neuropathy ...

In continuation of the work on the nature of the glycoside formation in the partially substituted sugars,’ a study of the 5methyl glucose described by Ohle and von Vargha2 was undertaken by us. On the basis of previous experience, a substance of this structure was expected to form but one glucoside, the furanoside, and it was therefore surprising to find indication of the formation of two gluco...
