Purple eggplant fruits often turn brown during maturity stages, severely influencing their market value and shelf life. However, the metabolites and genes accounting for the fruit color changes are largely unknown. Here, metabolites and gene expression analyses were used to explore the candidates underlying the differences in fruit color changes between two eggplant genotypes, ‘14-345’ and ‘CGN23829’, with contrasting fruit color changes during fruit development. We found that flavonoids are the most differentially accumulated metabolites between ‘14-345’ and ‘CGN23829’. Higher contents of D3R and D3G are important for keeping the purple color at the maturity stage. Naringenin chalcone likely accounts for the color changes from purple to brown in ‘14-345’. Notably, at the physiological maturity stage, lower expression of early biosynthetic genes (EBGs) involved in the flavonoid biosynthesis pathway is important to keep lower contents of metabolites upstream of anthocyanins, thus leading to more purple coloring. Taken together, the results indicate that delphinidins and naringenin chalcone play important roles in determining eggplant fruit color changes at maturity stages, which is helpful for further dissecting the mechanisms underlying fruit color differences and changes in eggplants.
