Abstract:

To identify the volatile oil components in Dendrobium officinale, D. nobile and lily flowers, N-hexan-water distillation method was used to extract volatile oil from D. officinale, D. nobile and lily flowers, analysis of their chemical components were conducted by gas chromatography-mass spectrometry (GC-MS). A total of 83 chemical components were identified from the three flowers. 50, 68 and 22 chemical components were isolated from D. officinale, D. nobile and lily flowers, respectively, and 47, 57 and 16 chemical components were identified. Their relative contents accounted for 91.72%, 70.79% and 83.94% of the total volatile oil, respectively. Among the aroma components, 17, 25 and 5 were identified, accounting for 11.34%, 27.61% and 24.37%, respectively. The main aroma components in D. officinale flowers were ethyl palmitate, ethyl linoleate, cetyl aldehyde and chlorophyl alcohol. The main aroma components of D. nobile flowers were palmitic acid, ethyl palmitate, ethyl linoleate, caryophyllene, α-terpinol, 4-ethyl-2-methoxyphenol. The main aroma components of lily flowers were ethyl palmitate, ethyl linoleate and ethyl oleate.
