 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). \\ Major constituents of the vacuum headspace concentrate of the flower volatiles were acetophenone (20%), linalool oxides (11.5%), and indole (10%).

 1,4-Dihydro-2-methyl-2H-3,1-benzoxazine (odor: quinoline-like) as the cyclic product of anthranilic alcohol and acetaldehyde is found in the vacuum headspace concentrate of a P.coronarius flowers variety in amounts of 0.2-1%. In pure form it cleaves acetaldehyde in perceptible amounts. \\ 1,4-Dihydro-2-methyl-2H-3,1-benzoxazine (odor: quinoline-like) as the cyclic product of anthranilic alcohol and acetaldehyde is found in the vacuum headspace concentrate of a P.coronarius flowers variety in amounts of 0.2-1%.
