| comparing wild american grapes with vitis vinifera: a metabolomics study of grape composition. | we analyzed via untargeted uhplc-esi-q-tof-ms the metabolome of the berry tissues (skin, pulp, seeds) of some american vitis species (vitis cinerea, vitis californica, vitis arizonica), together with four interspecific hybrids, and seven vitis vinifera cultivars, aiming to find differences in the metabolomes of the american vitis sp. versus vitis vinifera. apart from the known differences, that is, more complex content of anthocyanins and stilbenoids in the american grapes, we observed higher pr ... | 2015 | 26158394 |
