Resveratrol and Piceid Metabolites and Their Fat-Reduction Effects in Zebrafish Larvae
Zebrafish, 2013Abstract Resveratrol, a polyphenolic phytoalexin found in many plants, has been reported to have antiobesogenic effects in several animal and in vitro models. Zebrafish present several technical advantages that place them at an interesting, halfway point between

Analytica Chimica Acta, 2011
For the first time, a spectrofluorimetric method is reported for the simultaneous determination of resveratrol (RVT) and piceid (PCD), two stilbenes showing diverse interesting physiological and biochemical attributes, as well as a wide range of health benefits ranging from cardioprotection to chemoprevention.

Liquid Chromatographic Determination of Resveratrol and Piceid Isomers in Honey
Food Analytical Methods, 2011In this work, a liquid chromatography method with diode array and fluorescence detection and electrospray ionization mass spectrometry (LC-DAD-FLD and LC-ESI-MS) has been developed for the determination of residues of resveratrol in all its forms (free isomers and glycosylates) in honey.

trans-Resveratrol and trans-Piceid Content of Hungarian Wines
Chromatographia, 2010Plant polyphenols are naturally occurring secondary plant metabolites, synthesized in response to environmental stress factors. As anti-oxidants and free-radical scavengers they serve as essential components of the human diet. Among polyphenols well studied representatives are the trans-resveratrol and trans-piceid molecules, the latter being the ...

Piceid (Resveratrol Glucoside) Synthesis in Stilbene Synthase Transgenic Apple Fruit
Journal of Agricultural and Food Chemistry, 2006A stilbene synthase gene along with the selectable marker gene bar for herbicide resistance was transferred via Agrobacterium tumefaciens mediated transformation into apple (Malus domesticaBorkh.) cvs. 'Elstar' and 'Holsteiner Cox'. The stilbene synthase catalyzes the conversion of 1 molecule of p-coumaroyl-CoA and 3 molecules of malonyl-CoA into 3,4 ...

HPLC determination of resveratrol and piceid from circassian fruit wine
2011 International Conference on New Technology of Agricultural, 2011This study established a assay of resveratrol and piceid from circassian fruit wine. The optimum pretreatment conditions were pH 2, extraction temperature at 4 °C and ethyl formate as extraction solvent. Conditions of HPLC were conducted the mobile phase program of gradient elution with acetonitrile and water, detected trans-resveratrol and trans ...

Transport, deglycosylation, and metabolism of trans-piceid by small intestinal epithelial cells
European Journal of Nutrition, 2006Numerous epidemiological and animal studies have shown that consumption of red wine is related to reduced incidence of cardiovascular diseases and cancer. Trans-resveratrol (3, 5, 4'-trihydroxystilbene), a phenolic compound present in wine, has been reported to have a potential cancer chemopreventive activity. Moreover, it may exert a protective effect

Preformulation Stability of trans-Resveratrol and trans-Resveratrol Glucoside (Piceid)
Journal of Agricultural and Food Chemistry, 2010Resveratrol and resveratrol glucoside (piceid) were evaluated in a preformulation stability study. An HPLC assay was used for the analysis of stressed/reference samples. Samples of solid, crystalline material were held under the following conditions: 40 degrees C/75% RH (both open and protected), ambient fluorescent light (open), 70 degrees C (open ...

Maximising resveratrol and piceid contents in UV and ultrasound treated peanuts
Food Chemistry, 2009Abstract The effects of varying doses of UV and ultrasound (US) treatments on the concentrations of resveratrol, piceid and total stilbenes, and sensory overall acceptance of peanuts were evaluated using response surface methodology.

Evolution of Resveratrol and Piceid Contents during the Industrial Winemaking Process of Sherry Wine
Journal of Agricultural and Food Chemistry, 2010In the Jerez region, the sherry winemaking process involves a stage of aging carried out in a dynamic system known as "soleras" and "criaderas". In the case of fino sherry, this aging takes place in the presence of a yeast film growing on the surface of the wine, which gives it a very specific character.
