两种不同寄主桑寄生挥发油成分分析

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.

Chemical Constituents of Essential Oils from Two Different Host of Taxillus chinensis

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.
