脱皮马勃挥发性成分的GC-MS分析

目的:分析脱皮马勃的挥发性成分,为脱皮马勃的开发利用提供实验依据.方法:利用水蒸气蒸馏法提取脱皮马勃(Lasiosphaera fenzlii Reich)挥发油,采用气相色谱-质谱联用(GC-MS)技术对挥发油进行分析.结果:共分离出89个化学成分,鉴别出49个化学成分,占挥发油总量的70.713％,其主要成分为苊(16.836％)；芳-姜黄烯(7.800％)；丁香烯环氧物(5.448％)；β-姜黄酮(2.814％)；β-杜松萜烯(2.771％).结论:首次采用气相色谱-质谱联用法对脱皮马勃的挥发性成分进行研究.

GC-MS Analysis of Volatile Constituents of Lasiosphaera fenzlii

Objective: To provide the foundation for reasonable utilization by analyzing the volatile constituents of Lasiosphaera fenzlii. Method: The volatile oil was extracted from L. fenzlii by team distillation. The chemical constituents were analyzed by GC-MS. Result: Eighty nine compounds were separated and forty nine of them were identified, which accounted for 70.713% of all the volatile oil. The major components were acenaphthylene (16.836%), ar-curcumene (7.800%), caryophyllene oxide (5.448%), beta-tumerone(2.814%), beta-cadinene(2.771%). Conclusion: This paper reported, for the first time, the composition of volatile oils of L. fenzlii by GC-MS.
