“…Floral scent emission patterns often match the activity pattern of pollinators, so they are often investigated from both ecological and systematic perspectives (Meekijjaroenroj et al, 2007). Aroma emission generally starts when the flower is fully opened and peaks during periods when pollinators are most active (Dudareva and Pichersky, 2000;Jiang et al, 2011;Pichersky et al, 2006).…”

Floral scents emitted from eight cultivars of cut lily flowers (Lilium) were analyzed. Floral volatiles were collected by headspace adsorption on sorbent tubes and analyzed by gas chromatography–mass spectrometry (GC/MS) using a direct thermal desorption. Fifty volatile compounds were identified. Nine compounds were detected in all lilies, whereas 20 compounds were detected in all scented lilies. The results revealed that non-scented lilies emitted trace amounts of volatile compounds, whereas scented lilies emitted high levels of volatile compounds. Monoterpenoids and benzenoids were the dominant compound classes of volatiles emitted from scented lilies. Myrcene, (E)-β-ocimene, linalool, methyl benzoate, and ethyl benzoate were the major compounds of the aroma of scented lilies; 1,8-cineole was also a major compound in the two scented oriental × trumpet hybrid lilies. Scent emissions occurred in a circadian rhythm with higher levels of volatiles emitted during the night. Lilium ‘Siberia’ was selected as a model to investigate the source of the emissions. GC/MS analysis of four flower parts and neutral red staining revealed that tepals were the source of floral scent.

“…A number of authors have reported on failed efforts to use floral scent chemistry for phylogenetic analysis ( Williams and Whitten, 1999 ; Levin et al, 2003 ; Meekijjaroenroj et al, 2007 ) and as far as we know only two studies have yielded credible phylogenetic patterns ( Barkman, 2001 ; Raguso et al, 2006 ). One possible explanation is that the number of species and especially the number of VOCs used in the studies that failed was quite low.…”

“…In male euglossine bee-pollinated orchids, floral fragrance data did not reliably indicate phylogeny ( Williams and Whitten, 1999 ). In two genera of Nyctaginaceae, and in four Licuala species (Arecaceae) flower VOCs did not reflect classification ( Levin et al, 2003 ; Meekijjaroenroj et al, 2007 ). While phylogenetic relations based on major floral VOCs revealed no distinct patterns at higher taxonomic levels ( Knudsen et al, 2006 ), phylogenetic patterns were detected in Cypripedium (Orchideaceae) ( Barkman, 2001 ) and within Nicotiana ( Raguso et al, 2006 ).…”

Floral Volatiles in Parasitic Plants of the Orobanchaceae. Ecological and Taxonomic Implications

et al. 2016

The holoparasitic broomrapes, Orobanche spp. and Phelipanche spp. (Orobanchaceae), are root parasites that completely depend on a host plant for survival and reproduction. There is considerable controversy on the taxonomy of this biologically and agronomically important family. Flowers of over 25 parasitic Orobanchaceae and a number of close, parasitic and non-parasitic, relatives emitted a complex blend of volatile organic compounds (VOCs), consisting of over 130 VOCs per species. Floral VOC blend-based phylogeny supported the known taxonomy in internal taxonomic grouping of genus and eliminated the uncertainty in some taxonomical groups. Moreover, phylogenetic analysis suggested separation of the broomrapes into two main groups parasitizing annual and perennial hosts, and for the annual hosts, into weedy and non-weedy broomrapes. We conclude that floral VOCs are a significant tool in species identification and possibly even in defining new species and can help to improve controversial taxonomy in the Orobanchaceae.

“…They can be referred to as active secondary metabolites from plants because they are very potent at trifling amounts which due to large number of compounds that often define their composition [1], [2]. Floral scents are presumed to have evolved during the course of evolution to guarantee subsistence, and this could explain their dual functions in many plants -they attract pollinators but also contain compounds that act to dissuade herbivory [3].…”

Despite its use in traditional medicines, studies on the radical scavenging activity of the essential oils from Xylopia aethopica from Nigeria have not been widely reported in literature. Thus, in this work, fresh fruits of Xylopia aethopica were air dried, ground and extracted through hydro-distillation using Clevenger-type distillation apparatus. The essential oil was analyzed using Gas Chromatographic/Flame Ionization Detection (GC/FID) Technique and confirmed by gas chromatographic/mass spectrometric (GC/MS) analysis. The radical scavenging activity of the essential oil was evaluated in comparison with butylated hydroxylanisole (BHA) through 1,1-Diphenyl-2-picrylhydrazyl (DPPH) scavenging assay. A total of Forty-five compounds were detected through the GC/FID and GC/MS analyses of the essential oil of Xylopia aethopica. The major constituents of the essential oil were β-pinene (55.15%), α-thujene (9.23%) and α-eudesmol (8.61%) and α-pinene (6.77%). Other notable constituents were 1, 8-cineole (6.13%), ethyl cinnamate (5.83%) and elemol (5.17%). The methanolic solution of the essential oil showed concentration-dependent scavenging activity on 1,1-Diphenyl-2-Picrylhydrazyl (DPPH) radical. The results of the Scavenging effect of the Xylopia aethopica essential oil compared well with the activity of the commercial radical scavenging agent, Butylated hydroxylanisole (BHA) and this suggests possible uses of the essential oil as sources of natural antioxidants. Data were analyzed using R statistical software.
