A method, including solid phase extraction sample preparation, overpressured layer chromatographic separation, and subsequent densitometric evaluation, was developed for measurement of total resveratrol (cis- and trans-isomers) content of wine. The a

On the basis of our earlier observations, preliminary experiments were conducted with the fire blight pathogen Erwinia amylovora with the BioArena system using the potential antibacterial substances 1′-methylascorbigen (MeAG) as formaldehyde (HCHO)

Using OPLC separation and subsequent biodetection with Pseudomonas savastanoi pv. phaseolicola antibacterial compounds have been detected in both red and white wine extracts. However, the microbicidal power of red wine extracts was, in all cases, hig

A simple method is described for separation and determination of the isomers of trans-resveratrol and related compounds from different types of red wine by overpressured layer chromatography (OPLC). Comparison of OPLC with TLC clearly showed the adva

BioArena as a complex bioautographic system was successfully used for studying mechanism of action of some characteristic plant ingredients (e.g., 1'-methyl-ascorbigen, trans-resveratrol, salicylic acid, cinnamic acid). It has been established that t

Experimental data suggest that Resveratrol, a compound found in grapes and other fruits may influence cell proliferation and apoptosis. The aim of our experiments was to study the effect of Resveratrol on tumor cell cultures and an endothelial cell c
