摘要: 为明确库买提杏中主要类胡萝卜素组分及含量,应用高效液相色谱-二极管阵列检测-大气压化学电离-质谱技术获取其色谱、质谱和光谱信息并与标准品信息相比较,分析鉴定杏中主要的类胡萝卜素,利用高效液相色谱定量检测鲜杏中主要类胡萝卜素。结果表明:库买提杏中主要含有β-胡萝卜素、α-胡萝卜素和β-隐黄素以及顺式异构体等类胡萝卜素组分,其中β-胡萝卜素含量(以干基计算)高达114?μg/g,说明库买提杏中蕴含丰富的β-胡萝卜素,可以作为人体获取β-胡萝卜素的食物来源。

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.
