| Abstract: | In this study, trans-resveratrol levels were determined in 147 Iranian grape cultivars using a modified extraction and gradient HPLC procedure with photodiode array detection. It was found that 41 out of 147 cultivars contained significant levels of trans-resveratrol. The detected amounts ranged from 0.98 to 6.25 mg kg?1 fresh weight with a mean value of 3.59 (white grapes) and 3.08 mg kg?1 (red grapes), respectively. |
