云南、四川两产地菖蒲挥发油的化学成分分析

目的:分析不同产地菖蒲挥发油的化学成分,为菖蒲的进一步开发利用提供科学依据。方法:采用水蒸气蒸馏法从菖蒲中提取挥发油,用气相色谱-质谱法对挥发油中化学成分进行分析,以归一化法计算各种化学成分的相对含量。结果:从云南产菖蒲中鉴定出39种化学成分,占挥发油总量的80.51%;四川产菖蒲中鉴定出37种化学成分,占挥发油总量的81.96%;两产地菖蒲挥发油中含有31种相同成分。云南产菖蒲中含量最高的是β-细辛醚(13.46%),四川产菖蒲中含量最高的是α-细辛醚(10.01%)。结论:本研究结果可为菖蒲的进一步开发利用提供科学依据。

Study on Chemical Constituents of Essential Oil from Acorus calamus from Two Different Habitats

OBJECTIVE： To analyze the chemical constituents of essential oil of Acorus calamus from different habitats in order to provide scientific basis of exploitation of A.calamus.METHODS： The essential oil was extracted from A.calamus by steam distillation.The chemical constituents were analyzed by GC-MS.The relative contents of chemical constituents were calculated using normalization method.RESULTS： 39 kinds of chemical components were identified in A.calamus from Yunnan province,accounting for 80.51% of total amount of essential oil.37 kinds of chemical components were identified in A.calamus from Sichuan province,accounting for 81.96% of total amount of essential oil.There were 31 kinds of same chemical constituents in A.calamus from Yunnan province and Sichuan province.The content of β-asarone was highest in A.calamus from Yunnan province （13.46%） and that of α-asarone was highest in A.calamus from Sichuan province （10.01%）.CONCLUSION：The study can provide scientific basis for the further development of A.calamus.
