Narcissus trevithian and Narcissus geranium: Analysis and synthesis of compounds
摘要:
The essential oils of two narcissus varieties, Narcissus trevithian and Narcissus geranium, obtained by extraction of flowers followed by high vacuum distillation of the absolute, were analyzed by GC/MS. After separation in fractions, unknown compounds were isolated by preparative GLC and their structures established by NMR/IR spectroscopy. The synthesis of a number of new compounds, found for the first time in narcissus oil, is described. The two narcissus species are compared with respect to their main components and odor quality. All compounds found so far in narcissus varieties are listed.
