Abstract
In order to analyze and compare the anthocyanin characteristic of red wine grapes with diverse genetic backgrounds, skin anthocyanins among 21 different cultivars belonging to Vitis vinifera L., and hybrids were evaluated. A total number of 24 anthocyanins were identified and quantified by UPLC-PDA-MS/MS. Total contents of anthocyanins varied significantly among the different grape groups. The large variability in the anthocyanins compositions were obvious between V. vinifera and non-V. vinifera grapes and also between the grapes originating from Europe and North America were observed. According to clustering and principal component analysis, tested grape cultivars were divided into four groups with similarity to their anthocyanins content and compositions.
