Tzvel. at Different Altitudes %D 2020 %R 10.7525/j.issn.1673-5102.2020.05.018 %J Bulletin of Botanical Research %P 782-788 %V 40 %N 5 %X The aerial parts of Ajania tenuifolia(Jacq.) Tzvel. growing in different regions were collected as raw materials, and the volatile oil was extracted by water distillation. The chemical constituents of volatile oil were analyzed by GC-MS. The correlation between common components and altitudes was studied by SPSS 22.0 statistical software. The volatile oil components of A.tenuifolia were significantly different at different altitudes. There were five common components:camphor, α-pinene, β-pinene, eucalyptol, (-)-terpinen-4-ol. The chemical substances with the highest content of volatile oil at each altitude were eucalyptol, camphor, o-cymene, camphor, and eucalyptus. The same compound with a relative content of more than 5% at each elevation is only eucalyptol. By correlation analysis the content of these five common components was not significantly correlated with altitude. The altitude has no regular influence on the content of essential oils. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2020.05.018
