+The highly fragile flowers open during twilight which for the following night emit a pleasing scent "...based on constituents also important to gardenia and honeysuckle species, just to mention the characteristic accord generated by linalool, jasmone, (Z)-hex-3-enyl benzoate, methyl jasmonate, jasmine lactone and indole." Main compounds found in the headspace of living flowers were (E)-ocimene (47.5%), (Z)-ocimene (4.8%), methyl salicylate (8.0%), linalool (7.5%), benzaldehyde (5.1%), benzyl alcohol (3.9%), and 2-phenylethyl alcohol (3.1%). Olfactory most important components were jasmone (0.3%), methyl trans (Z)-jasmonate (0.2%), jasmine lactone (0.07%) and indole (1.0%).\\
