摘　　要：为了解槐枝中挥发油的化学成分,为其开发利用提供依据,采用水蒸汽蒸馏法分别提取新鲜和干燥槐枝中的挥发油,用气相色谱-质谱联用法分析和鉴定其化学成分。结果表明:新鲜槐枝挥发油中分离出60种成分,鉴定出58种,占挥发油总量的97.73%;干燥槐枝挥发油中分离出56种,鉴定出46种成分,占挥发油总量的92.86%。新鲜和干燥槐枝挥发油的主要成分为棕榈酸、亚油酸和油酸,其相对含量在新鲜槐枝中分别为39.53%、16.04%和6.98%,在干燥槐枝中分别为33.74%、7.59%和4.48%。新鲜和干燥槐枝中的挥发油化学成分存在差异。The volatile oil from fresh and dried branches of S.japonica was hydro-distilled and analyzed by GC-MS to provide references for its exploitation and utilization.The results showed that 58compounds were identified,representing 97.73% of the fresh branches of S.japonica volatile oil,whereas in the dried branches of S.japonicavolatile oil,only 46compounds were identified,representing 92.86%.The main components of fresh branches of S.japonica were palmitic acid（39.53%）,linoleic acid（16.04%） and oleic acid（6.98%）;The main components of dried branches of S.japonica were palmitic acid（33.74%）,linoleic acid（7.59%）and oleic acid（4.48%）.There are significant differences between volatile oil from fresh and dried branches of S.japonica.
