From the flowers emanate a cocoa and dark chocolate scent, „combined in a discrete aromatic-floral frame… the main constituent (-)-(R)-1-methylbutyl benzoate, representing 87% of the volatiles, forms the basis of this unique scent, accompnaied by a great number of olfactorily and structurally interesting minor compounds such as 1-methylbutyl nicotate (0.3%) or 1-methylbutyl cinnamate (0.02%).“
