    Abstract：ObjectiveTo analyze chemical constituents of the volatile oil from Solynum larytum Thunb.MethodsThe volatile oil was extracted from Solynum larytum Thunb.by steam distillation. The components of the volatile oil were separated and identified by GCMS. The relative content of each component was determined by area normalization.ResultsOne hundred and fifty- four kinds of components were separated. Among them, fortyseven components were identified, accounting about 83.23% of the total volatile oil.ConclusionHexadecanoic acid and linoleic acid are the most abundant components with the concentration of 42.79% and 19.97% respectively. ......
