In particular methyl isoleucinate contributes to the special odor of the fresh flowers. Literature-mentioned amines like ethylamine, isobutylamine and isoamylamine could not be found, but imines derived from isoleucine methyl ester with acetaldehyde (0.15%), butanal (0.1%), and acetone (0.15%), definitely identified with authentic samples and GC. \\
