Abstract: In order to determine the composition and content of carotenoids in fresh Kumaiti apricot (Prunus armeniaca L.), the major carotenoids were analyzed by high performance liquid chromatography-diode array detection-atmospheric pressure chemical ionization-mass spectrometry (HPLC-DAD-APCI-MS) and were identi?ed by comparison of their chromatographic, spectroscopic and mass spectral data with those of reference standards or those reported in the literature. An external standard method was applied to quantify the carotenoids. Results: β-Carotene, α-carotene, β-cryptoxanthin and their cis isomers were found to be the main carotenoid components in Kumaiti apricot, and its β-carotene content was up to 114 μg/g dry sample. In conclusion, Kumati apricot is rich in β-carotene and is a good dietary source of β-carotene.
