Chrysanthemum is one of the four major cut flowers in the world, with high ornamental and economic value. Fragrance is an important ornamental character of chrysanthemum flowers, especially those consumed as tea and other foods, and the flower fragrance is the major determinant of the commercial value of chrysanthemum cultivars. Currently, however,...

Many new hybrids of chrysanthemums from Indonesia are adapted to tropical areas. The hybrids were growing well with many characteristics such as consumer preferences and the idiotype of chrysanthemums. The goal of the research was to collect, select and categorize new chrysanthemum hybrids to be the parent’s resource for new breeding. They were Pus...

Herbaceous peony (Paeonia lactiflora Pall.) is a well-known and traditional flower in China, occupying a significant position in Chinese traditional culture. The floral scent of the herbaceous peony however remains relatively understudied. The objective of this study was to investigate the floral composition of herbaceous peony by collecting and identifying floral volatiles from 100 cultivars, including P. lactiflora 'Hangbaishao', P. lactiflora 'Hongrongqiu', P. lactiflora 'Biandihong', P. lactiflora 'Zijin Daipao', P. lactiflora 'Zixia Yingxue', and P. lactiflora 'Fenchi Dicui'. The volatile compounds were collected using the dynamic headspace technique and identified through gas chromatography-mass spectrometry (GC-MS). The results demonstrated qualitative and quantitative variations in the floral fragrances emitted by the 100 cultivars, with a total of 16 volatiles belonging to six categories (six alkanes, three alcohols and esters, two terpenes, as well as one each of ether and phenol) being identified. However, it is notable that not all volatile categories were emitted by every cultivar. Moreover, while some compounds were present in all 100 herbaceous peony cultivars, others were exclusive to specific cultivars. The screening revealed that ten of the 16 identified flower volatile compounds exhibited unique floral components. It is noteworthy that benzene,1,4-dimethoxy-, was identified as the most prominent compound in several cultivars, including P. lactiflora 'Taohua Huancai', P. lactiflora 'Xishifen', P. lactiflora 'Dabanhong', P. lactiflora 'Fumantang', and P. lactiflora 'Zhushapan'. Furthermore, the clustering classification results demonstrated that benzene,1,4-dimethoxy-, exhibited the highest variable importance in projection (VIP) value of 3.153, as determined by partial least squares discriminant analysis (PLS-DA).
... Volatiles emitted from intact flowers of screened Clematis were collected in an open headspace sampling system (Analytical Research Systems, Gainesville, FL, USA) as previously reported with minor modification [8] . A single detached inflorescence in a single flask with 150 mL of distilled water were placed in a glass chamber (20 cm diameter, 50 cm tall) covered with a removable lid. ...
Floral scent is a crucial characteristic that greatly affects the reproductive process and also the market value of numerous ornamental crops. As the pivotal species in basal dicotyledonous, Clematis is widely favored as an ornamental vine plant due to its varied colors and shapes of flowers. However, the diversity and complexity of the floral fragrance in Clematis is largely unexplored. Thus, on the basis of the initial sensory survey, four fragrant wild Clematis species and five cultivars were selected to investigate the variation of the floral volatile profiling between the wild Clematis species and their cultivars. Our results demonstrated that a total of 162 volatile compositions, including terpenoids, benzenoids, fatty acid derivatives, and N-containing compounds, were successively detected by the combination of dynamic headspace collection and GC-MS analysis. The qualitative and quantitative comparison combined with clustering and PCA analysis indicated the interspecific discrepancy in floral volatiles between the wild Clematis species and cultivars. C. finetiana exhibited a higher emission with the characteristic releasing pattern being distinct from other species. In conclusion, the exploitation of the emission patterns, biosynthesis, and potential biological functions of floral scent, especially for terpenoids and methyl esters, provides a comprehensive understanding of volatile metabolism in fragrant Clematis species and their cultivars. These findings can be useful for aromatic resources screening and breeding strategies developing to create new aromatic cultivars of Clematis.
Chamomile (Matricaria recutita L.) is renowned for its therapeutic properties. This study offers a comprehensive analysis of Chamomile volatiles, employing Headspace Solid-Phase Microextraction (HS-SPME) coupled with Gas Chromatography-Mass Spectrometry (GC-MS). The methodology section outlines the extraction and analysis process, emphasizing the non-invasive nature of HS-SPME for capturing volatiles without altering their composition. The results display a diverse array of volatile constituents, encompassing sesquiterpenes, monoterpenes, and oxygenated compounds, each contributing uniquely to Chamomile’s fragrance and medicinal value. Although this abstract refrains from presenting specific figures or chromatograms, the outcomes underscore the complexity and diversity of Chamomile’s volatiles, warranting further exploration.
The discussion section interprets these findings in the context of Chamomile’s established health benefits, such as anti-inflammatory, antimicrobial, and sedative properties. This analysis establishes a foundation for understanding how Chamomile volatiles interact with biological systems, offering potential applications in aromatherapy and natural medicine. In conclusion, the study furnishes valuable insights into Chamomile’s volatile composition, elucidating the intricate chemical nature of this plant. These findings contribute to the broader body of knowledge surrounding Chamomile and may foster new opportunities for utilizing its volatiles in various therapeutic and aromatic applications. Further research is warranted to explore the full spectrum of Chamomile’s volatile compounds and their potential benefits for human health and well-being.
