Abstract

Objective To compare chemical components of essential oil extracted by 2 extraction methods.Methods The chemical component of essential oil from hemp seed was extracted by steam distillation extraction(SD) and supercritical fluid CO2 extraction(SFE-CO2).The yield of the oil by the 2 methods was compared,and the chemical component in the oil achieved by different extraction methods was also analyzed by GC-MS.Results Altogether 45 compounds were identified:43 by SFE-CO2 and 36 by SD.Conclusion The main components of essential with oil obtained the two methods are similar.
