摘要(Abstract):

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.
