摘　　要：目的:定性分析紫苏叶的挥发油。方法:利用气相色谱-质谱(GC-MS)法分离鉴定,同时用直观推导式演进特征投影法解析重叠色谱峰的二维色谱MS数据,获取组分的色谱曲线和MS。再根据组分的MS和保留时间进行库相似性检索以实现定性。结果:共分离解析出76种组分,其中19种组分在紫苏的相关GC-MS分析中未见报道。结论:GC-MS与直观推导式演进特征投影法分析紫苏叶挥发油成分可提供更多的信息。OBJECTIVE： To analyze qualitatively the volatile oil in Perilla leaves. METHODS： The chemical constituents in w）latile oil of Perilla stem were isolated and identified by GC-MS. The 2D MS data of the overlapped peaks were resolved with heuristic evolving latent projections（HELP） to obtain the chromatographic curve and MS（mass spectra）, and a qualitative analysis was performed by similar search in NIST library with the obtained MS and retention time. RESULTS： A total of 76 constituents were identified, of which, 19 had not been reported in the relative GC- MS analysis of Perilla frutescens. COMCLUSION： More information of volatile oil in Perilla leaves was obtained by GC-MS analysis combined with HELP resolution method.
