摘　　要：[Objective]The aim was to identify the composition of pigments from Jujube fruit skin.[Method]Pigments were extracted from＇Lubei Dongzao＇,＇Lajiao Zao＇,＇Chengwu Dongzao＇,＇Dabailing＇and identificated by using high performance liquid chromatography-mass spectrometry（HPLC-MS）.[Result]The results showed that eight flavanols and four to five flavonols were detected,no anthocyanins was detected.The contents of flavonoids were differnt in four varieties.The contents of flavanols（11 mg/g） and flavonols（1.78 mg/g） in＇Dabailing＇ were one-time higher than other varieties.Quercetin 3 rutinoside was the major flavonol.[Conclusion]The research provided theoretical basis for further study on mechanism of Jujube pigment turnning into the red.[目的]鉴定枣果皮色素物质的成分。分别提取‘鲁北冬枣’、‘辣椒枣’、‘成武冬枣’和‘大白铃’果皮中的色素物质,并利用HPLC-MS技术进行色素物质的成分鉴定。[方法]在4个枣品种中均可检测到8种黄烷醇类物质,4～5种黄酮醇类物质,未检测到花色苷类物质。各类物质在不同品种中含量有所不同,其中‘大白铃’中含量最多,黄烷醇类物质和黄酮醇类物质含量分别为11和1.78mg/g,约为其他品种含量的1倍。槲皮素3-芸香苷是枣果皮中主要的黄酮醇类物质。[结论]为进一步研究枣果皮转红机制提供理论基础。
