Rezumat:

The color pigments from different sorts of red wine (Cabernet Sauvignon,
Merlot, and Burgundy) produced in different years, purchased
from the Recas and Minis Romanian wineries, were separated
using a new reversed-phase thin-layer chromatographic (RPTLC)
method. Chromatographic separation of the pigments was
performed on silica gel RP-18F254 with acetonitrile–water–formic
acid 40:58:2 (v/v) as mobile phase. Most of the natural pigments are
phenolic compounds with antioxidant activity that can be evaluated
by use of a stable free radical, for example DPPH (2,2-diphenyl-1-
picrylhydrazyl). The proposed RP-TLC method can be used in wine
monitoring to identify the origin of wine and to detect adulteration.
