Abstract:
OBJECTIVE：To compare the volatile components extracted from the roots ，stems and leaves of Gaultheria yunnanensis. METHODS ：Steam distillation method was used to extract the volatile oils from roots ，stems and leaves of G. yunnanensis. Chemical constituents were analyzed by GC-MS. NIST 2011 standard mass spectral library was adopted to select the chromatographic peak with a matching degree higher than 80，and combined with relevant literatures for identification. Relative percentages of chemical constituents were calculated by peak area normalization. RESULTS ：Totally 95 chromatographic peaks were detected in valatile oil from the roots of G. yunnanensis and 54 chemical constituents were identified ，accounting for 82.35％ of the total content of root volatile components. The constituents with relatively high content were methyl salicylate （20.30％）， n-hexadecanoic acid （19.86％），（Z，Z）-9，12-octadecadienoic acid （9.26％），phenanthrene（4.37％）and so on. Totally 69 chromatographic peaks were detected in volatile oil from the stems and leaves of G. yunnanensis and 46 chemical constituents were identified，accounting for 97.10％ of the total content of volatile components in stems and leaves. The constituents with relatively high content were methyl salicylate （86.72％），n-hexadecanoic acid （2.60％），（Z，Z，Z）-9，12，15-octadecatrienoic acid （1.25％） and so on. Both of them contained 16 common constituents such as alkenes esters ，acids and so on. CONCLUSIONS：The chemical constituents of volatile oils extracted from the roots ， stems and leaves of G. yunnanensis are mainly esters and acids. The components are similar to each other ，but the contents of acids in the roots and esters in the leaves and stems are higher.
