- Abstract:
- Grapevine (Vitis vinifera L) leaf samples of three defined age groups were investigated for concentration of selected sixteen polyphenols implementing the developmental stage of leaves. All in all, twelve polyphenols were detected above the limit of quantification with caftaric acid showing the highest concentrations. By studying differences in concentrations levels of individual polyphenols between the leavesxxx position on the shoot (insertion levels) trans- and cis-resveratrol-3-O-glucoside, (+)-catechin, caftaric acid, quercetin-3-O-glucoside and quercetin-3-O-glucuronide were identified as key markers with different concentrations on at least three of four sampling dates and analysed by LC-MS/MS. For future applications, the detected temporal polyphenolic pattern needs to be validated using additional cultivars of grapevine to establish a xxxpolyphenolic fingerprintxxx of grapevine leaves of different insertion levels.
