Compositional Analysis of Grape Berries: Mapping the Global Metabolism of Grapes.

ABSTRACT: To characterize the nutrients and bioactive compounds in grape berries and to explore the real cause of the "French paradox" phenomenon, we performed metabolomic analysis of 66 grape varieties worldwide using liquid chromatography-tandem mass spectrometry (LC-MS). A nontargeted metabolomics approach detected a total of 4889 metabolite signals. From these, 964 bioactive and nutrient compounds were identified and quantified, including modified flavonoids, medicinal pentacyclic triterpenoids, vitamins, amino acids, lipids, etc. Interestingly, metabolic variations between varieties are not explained by geography or subspecies but can be significantly distinguished by grapes' color, even after excluding flavonoids and anthocyanins. In our analysis, we found that purple grape varieties had the h
