Untargeted Metabolomics Analysis of Different Grape Varieties and Different Parts of Wine Grape Using Gas Chromatography and Mass Spectrometry Technique

Natural active compounds are an important key to the development and utilization of functional foods and medicine. In this study, the chemical diversity and varietal differences of wine grape were studied by using the untargeted metabolomics method based on gas chromatography-mass spectrometry (GC-MS), and the secondary metabolites of different cultivars and different parts were analyzed. A GC-MS-based metabolomic approach and chemometrics tools was used to identify potential active compounds in Vitis vinifera. The results showed that the content of active compounds in red wine varieties was higher than that in white wine varieties, and the content of active ingredients in grape seeds was significantly higher than that in fruits. In conclusion, this study analyzed the metabolite composition and differentiation of different wine grape fruits in Turpan as a whole, and is expected to lay a foundation for the study of wine grape and to provide a theoretical basis for development and utilization of the Dietary supplement and medicine on them.
