| Abstract: | Objective To compare the traditional hydrodistillation(HD) and microwave-assisted hydrodistillation(MAHD) for the extraction of essential oil from hydrocoty lesibthorpoioides lam.Methods The essential oil was extracted by HD and MAHD methods from hydrocoty lesibthorpoioides lam,respectively.The chemical components were analyzed by gas chromatography-mass spectrometry(GC-MS).Results Foty-three and 39 compounds were identified by MAHD and HD with 94.88% and 93.63% of their relative content in the total essential oil,respectively.Conclusion The main components of the volatile oil extracted by two methods are roughly the same but the relative content is significantly different,in which MAHD extraction get more kinds of components and have higher extraction efficiency than HD extraction. |
