[Objective] To research the chemical components in the essential oils from leaves of Tetracera sarmentosa( L.) Vahl by GC-MS.[Methods]Essential oils were extracted from the leaves of T.sarmentosa by steam distillation method.The chemical components were analyzed by GC-MS; and the relative content of each component was detected by peak area normalization method.[Results]A total of 47 chromatographic peaks were isolated and 19 chemical components were identified,accounting for 73.72% of the total essential oils.The main chemical components from leaves of T.sarmentosa were hexadecanoic acid( 41.59%),phytol( 11.10%),linoleic acid( 5.08%) and so on.[Conclusions]This research provided references for the quality control of the leaves of T.sarmentosa,as well as the further development and utilization of the leaves of T.sarmentosa.
