摘　　要：目的:研究寄主分别为桂花树和相思树桑寄生挥发油的化学成分。方法:采用水蒸气蒸馏法提取桑寄生挥发油,用气相色谱-质谱联用法分析鉴定其化学成分,用面积归一化法确定其相对含量。结果:寄主为桂花树桑寄生挥发油分离出85个色谱峰,鉴定其中52个化合物,占总量的77.08%;寄主为相思树桑寄生挥发油分离出97个色谱峰,鉴定其中29个化合物,占总量的67.40%。结论:水蒸气蒸馏法提取得到的2种不同寄主桑寄生挥发性成分及含量都有较大的差异。Objective： To study the chemical constituents of the essential oils from the host of Osmanthus fragran.and Acacia confusa.Method： The essential oils were extracted by steam distillation（SD） and analyzed by GC-MS.The relative content of each component was determined by area normalization.Result： 85 peaks of the essential oils from the Flos Osmanthi Fragrans were separated and 52 components were identified,which accounted for about 77.08% of the total essential oils.97 peaks of the essential oils from the Acacia Confusa were separated and 25 components of it were identified,that accounted for about 67.04% of the total essential oils.Conclusion： There are some differences in the principal chemical constituents and content of the essential oil from two different host of Taxillus chinensis extracted by SD.
