“…The compositions of H. annuus essential oils cultivated in north Alabama are very similar to those reported by Adams and co-workers for populations growing in the southern plains of the United States [35]. The essential oils of H. annuus from Pisa, Tuscany, Italy [36]; Lagos, Nigeria [37]; or from western United States [35] had much lower concentrations of α-pinene and correspondingly higher concentrations of germacrene D. In marked contrast to the essential oils of Helianthus, essential oils of Rudbeckia fulgida Aiton and Rudbeckia hirta L. (Asteraceae, Heliantheae) from north Alabama were devoid of α-pinene, but rich in sesquiterpene hydrocarbons [27].…”

Essential Oil Compositions and Antifungal Activity of Sunflower (Helianthus) Species Growing in North Alabama

et al. 2019

Helianthus species are North American members of the Asteraceae, several of which have been used as traditional medicines by Native Americans. The aerial parts of two cultivars of Helianthus annuus, "Chianti" and "Mammoth", and wild-growing H. strumosus, were collected from locations in north Alabama. The essential oils were obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The Helianthus essential oils were dominated by monoterpene hydrocarbons, in particular α-pinene (50.65%, 48.91%, and 58.65%, respectively), sabinene (6.81%, 17.01%, and 1.91%, respectively), β-pinene (5.79%, 3.27%, and 4.52%, respectively), and limonene (7.2%, 7.1%, and 3.8%, respectively). The essential oils were screened against three opportunistic pathogenic fungal species, Aspergillus niger, Candida albicans, and Cryptococcus neoformans. The most sensitive fungus was C. neoformans with minimum inhibitory concentration (MIC) values of 78, 156, and 78 µg/mL, respectively.

“…In terms of some components, this study was in agreement with the previous study on Helianthus annuus L. by Ceccarini et al (2004), which belongs to the same sunflower family as yacon, but the main compounds of the essential oil of yacon, such as β-phellandrene, β-cubebene and β-bourbonene were not detected at all in the Czech Republic study (Adam et al, 2005). These differences could be related to the distinct habitat in which the plant was collected, the developmental stage and seasonal variation.…”

The essential oil from the leaves of yacon grown in China was isolated by hydrodistillation and distillation-extraction. Chemical constituents of the essential oil were separated and identified by means of gas chromatography/mass spectrometry (GC/MS) for the first time, and the relative content of each constituent was determined by area normalization. Twenty-one chemical constituents were identified, and their amounts accounted for 96.2% of the total composition. The main components of the essential oil were β-phellandrene (26.3%), β-cubebene (17.7%), β-caryophyllene (14.0%) and β-bourbonene (10.2%). Therefore, in the volatile oil from the leaves of yacon, sesquiterpenes are major compounds, accounting for 52.2%.

“…Mono-and sesquiterpenes have already been reported as typical constituents of the H. annuus essential oils obtained from the whole flowers, even if quantitative differences were observed in the analyzed genotypes [21] [25] [31] [33]. With respect to the complex distribution of the various chemical classes, the pollen of the O and WC genotypes showed a similar trend in the contribution of their constituents to the aroma: i) monoterpene hydrocarbons and sesquiterpenes were the main constituents, ii) aliphatic hydrocarbons and their derivatives were present in much smaller amounts than terpenes, iii) among the hydrocarbons, the aliphatic, ketone, and alcoholic hydrocarbons were minor constituents in comparison with the aldehyde and ester derivatives ( Fig.).…”

Samples of fresh pollen grains, collected from capitula in full bloom from two genotypes of sunflower (Helianthus annuus L.) and characterized by a different color, i.e., white-cream (WC) and orange (O), were analyzed by the HS-SPME (headspacesolid phase microextraction)/GC/MS technique. This study defined for the first time the fingerprint of the sunflower pollen, separated from the disc flowers, to define its contribution to the inflorescence aroma. In the GC/MS fingerprints of the WC and O genotypes, 61 and 62 volatile compounds were identified, respectively. Monoterpene hydrocarbons (34% in O vs. 28% in WC) and sesquiterpene hydrocarbons (37% in O vs. 31% in WC) were ubiquitous in all samples analyzed and represented the main chemical classes. α-Pinene (21% in O vs. 20% in WC) and sabinene (11% in O vs. 6% in WC) were the dominant volatiles, but also a full range of aliphatic hydrocarbons and their oxygenated derivatives gave a decisive contribution to the aroma composition (10% in O vs. 12% in WC). In addition, dendrolasin (3% in O vs. 4% in WC) and some minor constituents such as (E)-hex-2-en-1-ol (0.4% in O vs. 0.1% in WC) were pointed out not only for their contribution to the pollen scent, but also for their well-known role in the plant ecological relationships. Having evaluated two pollen morphs with different carotenoid-based colors, the study sought to highlight also the presence of some volatile precursors or derivatives of these pigments in the aroma. However, the pollen aroma of the two selected genotypes made a specific chemical contribution to the sunflower inflorescence scent without any influence on carotenoid derivatives.
