摘　　要：目的:对桃仁脂肪酸进行气相色谱指纹图谱研究,为桃仁的质量评价提供依据。方法:利用毛细管气相色谱对桃仁脂肪酸进行分析,并利用GC-MS技术确认指纹图谱中的特征指纹信息,进行系统聚类和相似度分析。结果:对34批不同产地、品种的桃仁进行了测定,获得了较为理想的包含特征信息的桃仁GC指纹图谱。结论:本方法重复性好,所建立的指纹图谱为桃仁药材的质量控制提供了有效手段。Objective： To investigate the GC fingerprint of fatty acids in peach seed, and provide evidences for quality assessment on peach seed. Method： Capillary gas chromatography was applied in analysis of fatty acids in peach seed, and the distinctive information was confirmed by GC-MS with hierarchical cluster and species similarity analysis. Result： The GC fingerprint containing distinctive information was obtained after investigation of peach seeds from 34 varieties and origins. Conclusion ： With Good reproducibility, fingerprints established for peach seeds provided an effective method for quality control.
