Analysis of Chemical Constituents of the Volatile Oil from Stems and Leaves of Sarcmdra glabra by GC-MS / 中国药房

ABSTRACT

OBJECTIVE: To analyze the chemical constituents of the volatile oil from the stem and leaves of Sarcandra glabra.METHODS: The volatile oil was extracted from the stem and leaves of Sarcandra glabra 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.RESULTS: 29 components in the volatile oil from the stem of Sarcandra glabra were identified,and their content representing 75.88% of the total volatile oil.64 components in the volatile oil from the leaves of Sarcandra glabra were identified,with their content representing 87.98% of the total volatile oil.CONCLUSION: The volatile from leaves and that from stems of Sarcandra glabra varied in the content of low molecular weight of chemical constituents,almost no low molecular weight of chemical constituent contained in the volatile oil in the stems.These data provide scientific bases for exploitation of Sarcandra glabra.
