This study was aimed to evaluate the preventive effect of the polyphenols from Chinese jujube peel (Ziziphus jujube Mill. cv. Dongzao) against myocardial injury (MI) induced by isoproterenol (ISO) and biotoxicity of aluminum in rats. The free phenols from jujube peel (JPFP) and the bond phenols from jujube peel (JPBP) were administered to rats by gastric(More)
Eicosapentaenoic acid (EPA), a well-known dietary n-3 PUFAS, has been considered to inhibit proliferation of tumor cells. However, the molecular mechanism related to EPA-induced liver cancer cells apoptosis has not been reported. In this study, we investigated the effect of EPA on HepG2 cells proliferation and apoptosis mechanism through mitochondrial(More)
This study was undertaken to determine the effectiveness of apple (Ralls) polyphenol extract (APE) in modulating aluminum chloride (AlCl3) induced hepatotoxicity in rats. The rats were distributed among 4 groups and fed different diets with or without AlCl3 (171.8 mg Al·kg(-1)·day(-1)) and APE (200 mg·kg(-1)·day(-1)) for 10 weeks. The activities of(More)
A new polysaccharide had been successfully isolated from maitake mushroom (Grifola Frondosa)-GFP. HPLC and Monosaccharide analysis showed that the average molecular weight of GFP was 155kDa and it was mainly composed of rhamnose, xylose, mannose, glucose, molar ratio of 1.00: 1.04: 1.11: 6.21. FTIR, methylation analysis and NMR were used to analyze the(More)
Aluminum (Al) has long been implicated in the pathogenesis of Alzheimer's disease (AD). Dietary polyphenols have been strongly associated with reduced risk of AD and the other nervous diseases. We aimed to evaluate the preventive effect of the apple polyphenol extract (APE) on Al-induced biotoxicity, in order to provide a new focus on the design of(More)
Aluminum (Al) has been well known as an environmental factor that may affect several enzymes and other biomolecules related to Alzheimer's disease. The increasing use of Al in the preparation and storage of food currently represents the main form of Al exposure for the general public. The present study was aimed to develop a household procedure for the(More)
We aimed at analyzing the structure of extracellular polysaccharide A from Grifola frondosa (EXGFP-A) and testing its immunomodulatory activity. Structural analysis shows that EXGFP-A was a contained α-D-glucoside bond and pyranose ring. GC analysis reveals that EXGFP-A was mainly composed of rhamnose, arabinose, xylose, mannose, glucose, galactose, by the(More)
We isolated a neutral polysaccharide from the fruiting body of a mushroom Grifola frondosa (GFP-A). The aim of this study was to characterize a neutral α-d-polysaccharide derived from G. frondosa and evaluate its immunomodulatory effect on toll-like receptor 4, mitogen-activated protein kinases and nuclear factor κB pathways of protein expression in(More)
A water-soluble polysaccharide (BP-1) was obtained from highland barley (Hordeum vulgare L.) by hot water extraction and purification of sepharose column chromatography. BP-1 had an average molecular weight of about 6.7×104Da and was composed of glucose (Glc), xylose (Xyl), arabinose (Ara) and rhamnose (Rha) with a relative molar ratio of(More)
Eicosapentaenoic acid (EPA), a typical kind of n-3 polyunsaturated fatty acids, has been considered to be a potent antitumor adjuvant. However, the mechanism related to EPA-induced SKOV-3 cell apoptosis has not been investigated. In this study, we elucidated the anticancer effect of EPA on SKOV-3 cells and its molecular mechanisms. The results of(More)
