Comparative metabolomics reveals differences in primary and secondary metabolites between "Shixia" and "Chuliang" longan (Dimocarpus longan Lour.) pulp.

ABSTRACT: Longan was a characteristic fruit for both medicine and food in China, which was rich in primary and secondary metabolites. Comprehensive high-throughput identification and comparison of metabolites in longan pulp among different varieties were still lacked. "Shixia" (SX) and "Chuliang" (CL) were the biggest major cultivars of longan in China. In this study, the content of total soluble solid, total flavonoid, and total phenolics indicated the difference of sweetness and bioactive compound content between the SX and CL pulp. Through a widely targeted metabolome, a total of 514 metabolites were identified and categorized into 23 groups mainly including flavonoids, amino acids & derivatives, lipids, phenolic acids, nucleotides & derivatives, alkaloids, organic acids and sugars & derivatives.
