Abstract/OtherAbstract:
The metabolite profiling of aqueous extracts of two peach varieties, namely Percoca Romagnola7 and Flaminia, with a different susceptibility to Ceratitis capitata attack was investigated by means of 1D and 2D high field NMR spectroscopy. Water soluble metabolites belonging to different classes such as organic acids (citric, fumaric, malic, quinic, shikimic, succinic acids), sugars (fucose, fructose, fructose-6-phosphate, glucose, glucose-6-phosphate, rhamnose, sucrose, and xylose), amino acids (alanine, asparagine, isoleucine, threonine and valine) and other metabolites such as myo-inositol, choline, trigonelline, catechin, chlorogenic and neochlorogenic acids, orthophosphate and a-L-glycerophosphorylcholine were identified. The metabolite profiling together with a suitable statistical analysis were used to make a comparison between the two varieties. The level of glucose, xylose, myo-inositol, choline, isoleucine and valine was found to be higher in Flaminia than in Percoca Romagnola7 samples whereas the level of fumaric acid, alanine, quinic acid, sucrose, fucose, chlorogenic, and neochlorogenic acid was found to be higher in Percoca Romagnola7 than in Flaminia samples.
