Abstract
The trunk stilbenoids of healthy and crown gall infected vines of Ojaleshi variety have been studied and identified as stress-metabolite compounds .Vine samples were taken from a 12-year-old vineyard cultivated on yellow soils type in Martvili region (Western Georgia). The stilbenoids were extracted by ethyl acetate and then separated in a chromatographic column and analyzed by the HPLC/MS method. The following stilbenoids have been detected: cis-piceid, trans-resveratrol, trans-ε-viniferin, cis-miyabenol C, cis-miyabenol. The concentrations were higher in infected vines as compared to the healthy ones. This is the first time that stilbenoids have been investigated in Ojaleshi grape variety.
