ABSTRACT

The headspace volatile compounds of the flowers of Plumeria tuberculata Lodd. were analyzed by solid phase microextraction coupled with capillary gas chromatography/mass spectrometry. Twenty-five compounds were identified, representing 100% of the total composition. The volatile fraction was characterized by oxygenated monoterpenes (79.6%), oxygenated sesquiterpenes (8.4%), sesquiterpene hydrocarbons (7.6%), and benzenoid esters (2.6%). The major components were geraniol (34.9%), citronelol (21.5%) and geranial (16.2%), and they were found to make the major contribution to the typical scent of this flower.
