摘　　要：目的研究广东尾叶桉叶挥发油的化学成分。方法采用水蒸气蒸馏法提取广东尾叶桉叶挥发油,用气相色谱-质谱联用技术进行分离测定,结合计算机检索技术对分离的化合物进行结构鉴定,应用气相色谱峰面积归一化法确定各组分的相对含量。结果首次确定了广东尾叶桉叶挥发油中38个化合物,所鉴定成分占总馏出峰面积的97.76%。主要成分为1,8-桉叶素(38.13%)、α-蒎烯(10.71%)、薄荷醇(9.79%)、α-松油醇(7.41%)、异蒲勒醇(5.51%)、右旋香茅醇(5.22%)、乙酸松香酯(5.03%)等。结论确定了广东尾叶桉叶挥发油的化学成分,与文献报道尾叶桉挥发油的成分具有相似性,但仍存在一些差异,为综合利用桉叶挥发油奠定了基础。Objective To investigate the chemical constituents of volatile oil from Eucalyptus urophylla S.T.Blakely leaves collected in Guangdong Province of China.Methods The volatile oil was extracted with steam distillation method,and analyzed by gas chromatography-mass spectrometry（GC-MS） method.The relative amount of each constituent was calculated by peak area normalization.Results Thirty-eight constituents in volatile oil from Eucalyptus urophylla S.T.Blakely leaves in Guangdong Province were identified,amounting to 97.76% of the total area of the peaks.The principal constituents were eucalyptol（38.13%）,alpha-pinene（10.71%）,menthol（9.79%）,alpha-terpineol（7.41%）,neomenthol（5.51%）,（R）-citronellol（5.22%）,alpha-terpinyl acetate（5.03%） and so on.Conclusion The constituents of the volatile oil from Eucalyptus urophyllaS.T.Blakely leaves in Guangdong Province were successfully identified.Compared with the reports,our findings suggest great similarity and little differences,which provides the foundation for further comprehensive utilization of the volatile oil.
