 +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." \\

 The comparative headspace analysis of flowers of a delicately scented yellow tea rose revealed interesting differences between living and picked flowers (living/picked): (Z)-3-hexenyl acetate (20.7/5.4%), hexyl acetate (8.4/4.3%), phenylethanol (5.7/3.3%), phenylethyl acetate (5.5/1.5%), 3,5-dimethoxytoluene (10.0/18.6%), α-elemene (0/4.1%), geranylacetone (2.2/0%), dihydro-β-ionol (0/2.6%), β-caryophyllene (0.3/2.1%), α-farnesene (5.8/3.0%). \\ The comparative headspace analysis of flowers of a delicately scented yellow tea rose revealed interesting differences between living and picked flowers (living/picked): (Z)-3-hexenyl acetate (20.7/5.4%), hexyl acetate (8.4/4.3%), phenylethanol (5.7/3.3%), phenylethyl acetate (5.5/1.5%), 3,5-dimethoxytoluene (10.0/18.6%), α-elemene (0/4.1%), geranylacetone (2.2/0%), dihydro-β-ionol (0/2.6%), β-caryophyllene (0.3/2.1%), α-farnesene (5.8/3.0%). \\
