Abstract

OBJECTIVE: To analyse chemical constituents of volatile oil from Dendranthema morifolium Tzvel. et Zhao. by GC-MS. METHODS: The volatile oil was extracted from Dendranthema morifolium Tzvel. et Zhao. by steam distillation and were analysed by different kinds of capillary columns to find out the optimal conditions. The content of compositions of volatile oil were determined by normalization method. And the constituents were identified by GC-MS. RESULTS: 41 components were separated and identified which accounted for over 73% of total volatile oil. CONCLUSIONS: The main constituents in the essential oils from Dendranthema morifolium Tzvel. et Zhao are verbenol, (-)-zingiberene, beta-sesquiphellandrene, farnesene, tau.-cadinol and tau.-muurolol.
