 Major constituents of the vacuum headspace concentrate of the flower volatiles were acetophenone (20%), linalool oxides (11.5%), and indole (10%). Among the minor constituents were 2-aminobenzaldehyde (2%), benzothiazole (1%), jasmone (trace), and (Z)-hexenyl benzoate (trace). \\

 Trans-myrtanal (46%), cis-myrtanal (2.2%), myrtenal, myrtenol, indole, nopinone (5.3%), 2-aminobenzaldehyde (11%), 2-formamidobenzaldehyde and veratraldehyde have been determined in the headspace of living flowers by GC-MS analysis. Flowers from another single plant showed an entirely different composition with hugh amounts of acetophenone (20%) and indole (10%). \\
