The composition of the volatile compounds isolated by simultaneous distillation-extraction (SDE) and headspace-solid phase microextraction (SPME) from flowers of Magnolia grandiflora growing in Cuba was investigated by GC/FID and GC/MS. Sixty-seven and thirty-four components were obtained by SDE and SPME, respectively. β-Pinene (10.5%), geraniol (7.4%) and germacrene D (6.2%) were the main constituents of the volatile oil isolated by SDE, while (E)-β-ocimene (24.6%), geraniol (18.9%), β-elemene (11.2%) and germacrene D (9.9%) were the most abundant in the headspace of the flowers, respectively.

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. Source

The chemical composition of the volatile compounds isolated by simultaneous distillation-extraction (SDE) and headspace-solid phase microextraction (SPME) from flowers of Michelia champaca growing in Cuba was investigated by GC/FID and GC/MS. Sixty-seven and thirty-four components were identified by SDE and SPME, respectively, with 1,8-cineole (22.8%) as the main constituent in the volatile oil isolated by SDE, and methyl benzoate (30.3%), indole (16.6%) and β-elemene (10.4%) the major components detected by SPME.

The headspace volatile compounds of the flowers of Clitoria fairchildiana R. A. Howard, Brunfelsia nitida Benth. and Crinum oliganthum Urban were analysed by solid-phase microextraction coupled with capillary gas chromatography/mass spectrometry. A total of 12, 16 and 13 compounds were identified in the flowers of C. fairchildiana, B. nitida and C.oliganthum, respectively. Monoterpene hydrocarbons and oxygenated monoterpenes were clearly dominant, accounting for over 96.5 and 82.3 % of the total volatiles in B. nitida, C. oliganthum flowers, respectively; while C. fairchildiana was rich in sesquiterpenes (96.8 %). Major constituents were linalol (93.6 %) in B. nitida, geraniol (32.6 %), (E)-β-ocimene (20.6 %) and an unknown compound (14.7 %) in C. oliganthum, and germacrene D (46.7 %) in C. fairchildiana flowers. © 2011, Har Krishan Bhalla & Sons.

The headspace volatile compounds of the flowers of Petitia domingensis Jacq. were analyzed by solid phase microextraction coupled with capillary gas chromatography/mass spectrometry. A total of 16 compounds were identified, representing 100% of the total composition. The major components were β- caryophyllene (35.7%), 4-methylanisol (18.0%) and α-pinene (12.5%). © 2012, Har Krishan Bhalla & Sons. Source
