摘要： The carotenoids in the peel and flesh of 41 apricot cultivars were qualitatively and quantitatively analysed by UHPLC-APCI-MS/MS, and the L*, a*, b* and quality indexes of the fruits were determined. The results showed that the L*, a*, b* and quality indexes of the fruits were quite different, and 13 carotenoids were detected in the peel and flesh of apricots, among which epsilon-carotene, alpha-cryptoxanthin and apocarotenal were newly detected carotenoids in apricots. The total carotenoid content of the 41 apricot cultivars varied from 20.983 to 320.278 mu g/g FW, and the total carotenoid content varied from 17.353 to 222.098 mu g/g FW in the peel and from 2.536 to 98.179 mu g/g FW in the flesh. The main components of apricot fruits were beta-carotene and (E/Z)-phy-toene, followed by beta-cryptoxanthin and lutein. This study shows that carotenoids in apricot fruits have rich metabolic diversity.
