More General and common knowledge of transresveratrol.
High-speed counter-current chromatography (HSCCC) was applied to the separation and purification of resveratrol and piceid from the dried roots (20.0 g) of Polygonum cuspidatium.
The EtOAc extracts were separated with chloroform-methanol-water (4:3:2, v/v). Resveratrol was identified in fraction 5. The water extracts were separated first with EtOAc-EtOH-water (10:1:10, v/v) and then with the same solvent system at the modified volume ratio of 70:1:70.
Yields of resveratrol and piceid obtained were 2.18% and 1.07%. Chemical structures of the purified resveratrol and piceid were confirmed by electrospray ionization MS and ^1H nuclear magnetic resonance spectroscopy.
A Validated HPLC Method for the Quantitative Analysis of Trans-Resveratrol and Trans-Piceid in Hungarian Wines:
A new, simple procedure for the determination of phenolic components of wines, such as resveratrol and piceid isomers, has been elaborated and validated. A set of 70 red wines and 3 white wines from two wineries (Polgar Winery and Bock Winery, Villany, Hungary) are analyzed by reversed-phase high-performance liquid chromatography.
The samples are injected without pretreatment and UV-vis and mass spectrometric (MS) detection has been applied. The detection limit for trans-resveratrol and for trans-piceid is found to be 0.9 and 0.6 pmol for the UV vis detection method and 0.3 and 0.2 pmol for the MS detection method. Trans-resveratrol and trans-piceid are found in red wines from 0.1 to 14.3 mg/L and from 3.8 to 16.4 mg/L concentrations, respectively.
