Figure Lengend Snippet: Chromatogram of all three stilbenes in full-scan (negative mode with electrospray ionization). 1: trans -resveratrol; 2: cis -ε-viniferin; 3: trans -ε-viniferin; 4: r2-viniferin.

Article Snippet: The trans -resveratrol standard (99%) along with commercialized standard of trans -ε-viniferin (95%) (Fig. ) were purchased from Sigma-Aldrich (Prague, Czech Republic), while the cis -ε-viniferin was generated from trans -ε-viniferin standard by UV exposition (Spectroline, CV-10, New York, USA).

Techniques:

( a ) trans -resveratrol, ( b ) cis -ε-viniferin, and ( c ) trans -ε-viniferin - Comparison of maceration (MAC) carried out for 1, 3, 7, and 14 days and Soxhlet extraction (SOX) for 3 hours, both in light and dark with respect to the yield of desirable components (white column), mg/g plant and their concentration in extracts (black column), wt.% (based on total mass of extract) with 95% confidence intervals.
