[Methods]Volatile oil components from different sites of N. jatamansi were identified and isolated by GC-MS. [Results] There were 56 kinds of volatile oil components from different sites of N. jatamansi,in which 39 components from herb of N. jatamansi,39 components from root and rhizome of N. jatamansi,and there were 22 common components. But 1 component in higher concentration had obvious difference. [Conclusions] The herb of N. jatamansi could not completely replace " root and rhizome" of N. jatamansi as the medicine,which was consistent with prior detection result of each physicochemical index from different sites of N. jatamansi. The research could provide the reference for making quality standard of N. jatamansi medicine and rational basis for its further research and development.展开更多
OBJECTIVE: To analyze the essential oils from flowers, leaves, stems, roots, and fruits of Chaihu(Radix Bupleuri Chinensis).METHODS: We extracted essential oils from different parts of Chaihu(Radix Bupleuri Chinensis)...OBJECTIVE: To analyze the essential oils from flowers, leaves, stems, roots, and fruits of Chaihu(Radix Bupleuri Chinensis).METHODS: We extracted essential oils from different parts of Chaihu(Radix Bupleuri Chinensis) using a steam distillation method. The essential oils were analyzed by gas chromatography-mass spectrometry(GC-MS). Data were collected in full scan mode(m/z 60-600). Volatile components were identified based on their retention indices and by comparing their mass spectra with those in the National Institute of Standards and Technology 2005 database assisted by tandem mass spectrometry information. The relative content of each constituent wasdetermined by area normalization.RESULTS: We identified 111 components, of which12 were common to all 5 parts, 30 were found only in roots, 14 were found only in flowers, 6 were found only in leaves, 4 were found only in stems,and 17 were found only in fruits.CONCLUSION: Our results show that the stems,flowers, leaves, and fruits of Chaihu(Radix Bupleuri Chinensis)contain a high concentration of essential oils, and that the exact composition of the essential oils differs among the plant parts. To develop new medicines and make full use of the Chaihu(Radix Bupleuri Chinensis)resource, it is important to characterize the essential oils from different parts of the plant. In future research, it will be important to determine the pharmacological effects of the various components and the essential oil mixtures.展开更多
