-The major volatile component (steam distillation) of the oil from fresh leaves (96.3%) and hay (46.8%) was coumarin. A.odoratum hay oil also contained alcohols like amyl alcohol (0.1%), (Z)-3-hexenol (0.1%), heptanol (0.1%), octanol (3%), (Z)-2-octenol (0.1%), and borneol (0.1%); methyl esters like methyl butyrate (0.7%), methyl valerate (0.3%), methyl hexanoate (0.6%), methyl octanoate (0.9%), methyl nonanoate (1.0%), methyl decanoate (0.3%), methyl dodecanoate (1.3%), methyl tetradecanoate (1.3%), methyl hexadecanoate (9.9%), methyl linolenate (3%) e.g.; (Z)-3-hexenyl acetate (0.1%); furthermore 4-vinylguaiacol (1.9%) and its methyl ether (0.3%); aldehydes like valeraldehyde (0.6%), hexanal (0.3%), octanal (0.1%), nonanal (0.3%), phenylacetaldehyde (0.1%), and benzaldehyde (0.1%). \\+The major volatile component (steam distillation) of the oil from fresh leaves (96.3%) and hay (46.8%) was coumarin.
