Abstract

To study the diversity and cultivar-specific of phytochemicals in bottle gourd, Gas chromatography-mass spectrometry (GC-MS)-based untargeted metabolomics method was used to analyze the metabolic profiles of two groups of bottle gourd cultivars exhibiting different tastes and flavors: fresh and slightly bitter (BBGs) / fragrant and sweet (SBG). A total of 155 metabolites (16 differential metabolites and 139 non-differential metabolites) were identified/annotated. The relative contents of 16 differential metabolites in BBGs are all higher than that in SBGs. The differential metabolites profiles of the two different groups were distinguished using principal component analysis (PCA), and the main differential metabolic pathways between the BBG and the SBG included those relating to plant nutrition and energy metabolism. This study provides new insights into the differences in metabolite profiles among bottle gourds with different tastes and flavors.
