摘要

Prunus armeniaca L. (apricot) is an economical tree widely cultivated for its nutritive and health benefits. Herein, we standardized apricot fruits and kernels for the first time in context to different cultivars and soil type using 1D and 2D NMR metabolomics leading to the identification of 23 metabolites belonging to sugars, amino acids, organic, phenolic, and fatty acids, flavonoids, sterols, vitamins, cyanogenic glycosides, and carotenoids accounting for apricot nutritive and sensory attributes. Multivariate data analysis revealed distinct metabolic differences between the fruits and kernels, with the fruits being higher in sugars, organic acids, and flavonoids, whereas kernels were richer in fatty acids, phytosterols, and amygdalin. OPLS-DA plot revealed apricots from sandy soil to be high in organic acids however those from muddy soil were rich in sugars. This study underscores the influence of soil type on the chemical composition of apricot fruits and kernels, of value for standardization and quality control purposes.
