Study on Chemical Constituents of Rhododendron dawuense at Different Altitudes
The differences in chemical constituents of Rhododendron dawuense at different altitudes are re-searched.The metabolites of Rhododendron dawuense at 3800m and 4200m altitudes by metabolomics are detec-ted,and the data were statistically analyzed by hierarchical clustering analysis(HCA)and principal component a-nalysis(PCA).The essential oil and pure dew of Rhododendron dawuense at 3800m,4000m,4200 altitude was prepared by water distillation method.The chemical constituents and content of the essential oil and pure dew were detected by gas chromatography-mass spectrometry(GC-MS).Results showed that there were significant differences in metabolites between the two altitudes.The results showed that the constituents and contents of es-sential oil and pure dew at 3800m and 4000m altitude were basically the same,and there were significant differ-ences between the essential oil and dew at 4200m altitude.There were significant differences in chemical composi-tion of Rhododendron dawuense at different altitudes.
