Ultraviolet irradiation of trans-resveratrol and HPLC determination of trans-resveratrol and cis-resveratrol in Romanian red wines.
A reversed-phase high-performance liquid chromatography method with diode array detection was developed for the determination of trans- and cis-resveratrol in red wines. Separation was achieved after direct injection by the use of a BDS Hypersil C18 column (250 × 4.6 mm) with gradient elution (solvent A: acetic acid 2%, solvent B: acetonitrile). Detection of trans- and cis-resveratrol was perfo...
متن کاملStereospecific determination of cis- and trans-resveratrol in rat plasma by HPLC: application to pharmacokinetic studies.
A simple, accurate, precise, specific and reproducible high-performance liquid chromatography (HPLC) method was developed for simultaneous determination of resveratrol isomers in rat plasma. Cis-resveratrol was made by exposure of a trans-resveratrol solution to sunlight for 5 days followed by separation by HPLC and identification by mass spectrometry (MS). The assay procedure involved simple l...
متن کاملMonitoring trans-Resveratrol in Grape Berry Skins During Ripening and in Corresponding Wines by HPLC.
Trans-resveratrol (3,5,4'-trihydroxy-trans-stilbene) is naturally present in the skin of grapes and therefore is expected to occur in grape products. Recently, there has been a renewal of interest in wine as medical treatment for various disorders. In this study, berry skins of five red grape varieties were analysed at weekly intervals for trans-resveratrol production, during 2012 and 2013 harv...
متن کاملTrans-, cis-, and dihydro-resveratrol: a comparative study
BACKGROUND Recent studies showed that moderate consumption of red or white wines increased the chances of breast cancer, while similar consumption of red wines, rich in trans-resveratrol (trans-R), decreased the rate of prostate cancer. This prompted us to explore the role of various forms of R in cancer proliferation. RESULTS Trans-R was found to be the most potent antiproliferative agent. C...
متن کاملtrans-Resveratrol as a neuroprotectant.
Epidemiological evidence indicates that nutritionally-derived polyphenols such as resveratrol (RES) have neuroprotective properties. Administration of RES to culture media protects a wide variety of neuronal cell types from stress-induced death. Dietary supplementation of RES can ameliorate neuronal damage and death resulting from both acute and chronic stresses in rodents. The specific molecul...
