Abstract:
The composition, differences, and metabolic mechanisms of phenolic compounds in fruits and peels of three different varieties (including Clausena lansium 'Jixin', 'Seedless' and 'Bingtang') were investigated. The results showed that the total phenolic content in the fruits followed the order CLB (2080.14 mg/kg) > CLS > CLJ, while in peels it followed CLSp (2457.56 mg/kg) > CLJp > CLBp. Significant differences were observed in flavanols, flavonols, lignans, and phenolic acids among samples. A total of 12 (in fruits) and 9 (in peels) differential phenolic compounds (VIP > 1) were screened. Compared with CLB, several antioxidants and antibacterial phenolics were significantly up-regulated in CLS and CLJ. Pathway analysis revealed that fruit differences were mainly enriched in phenylpropanoid biosynthesis and flavone/flavonol biosynthesis pathways, whereas peel differences were mainly enriched in flavonoid biosynthesis and flavone/flavonol biosynthesis pathways. These findings provided a theoretical basis for wampee variety identification, improvement, and functional evaluation.
