| | Main components of the headspace of hybrid tea roses were 1,3-dimethoxy-5-methylbenzene (1-74%), 2-phenylethanol (10-57%), citronellol (0-14%), and geraniol (0-45%). "...it is noteworthy that this compound [1,3-dimethoxy-5-methylbenzene] did not exist in the Rosa damascena and the Rosa centifolia as used in perfumery. This compound disperses a humid and fresh green note with a little phenolic and spicy character, and reminds us of a flower shop. This compound appeared to be the fragrance component that gave the scent of the tea rose and the hybrid tea rose a character distinct from that of the perfumery rose." \\ |
