“…The study showed that the main compounds of P. mume cultivars from the four aroma types were phenylpropanoids/benzenoids, which is consistent with many ornamental plants, such as M. ioensis [ 13 ], Rosa odorata and R. chinensis [ 24 ], P . axillaris [ 25 ], and Luculia pinceana [ 26 ].…”

Prunus mume is a traditional ornamental plant, which owed a unique floral scent. However, the diversity of the floral scent in P. mume cultivars with different aroma types was not identified. In this study, the floral scent of eight P. mume cultivars was studied using headspace solid-phase microextraction (HS-SPME) and organic solvent extraction (OSE), combined with gas chromatography-mass spectrometry (GC-MS). In total, 66 headspace volatiles and 74 endogenous extracts were putatively identified, of which phenylpropanoids/benzenoids were the main volatile organic compounds categories. As a result of GC-MS analysis, benzyl acetate (1.55–61.26%), eugenol (0.87–6.03%), benzaldehyde (5.34–46.46%), benzyl alcohol (5.13–57.13%), chavicol (0–5.46%), and cinnamyl alcohol (0–6.49%) were considered to be the main components in most varieties. However, the volatilization rate of these main components was different. Based on the variable importance in projection (VIP) values in the orthogonal partial least-squares discriminate analysis (OPLS-DA), differential components of four aroma types were identified as biomarkers, and 10 volatile and 12 endogenous biomarkers were screened out, respectively. The odor activity value (OAV) revealed that several biomarkers, including (Z)-2-hexen-1-ol, pentyl acetate, (E)-cinnamaldehyde, methyl salicylate, cinnamyl alcohol, and benzoyl cyanide, contributed greatly to the strong-scented, fresh-scented, sweet-scented, and light-scented types of P. mume cultivars. This study provided a theoretical basis for the floral scent evaluation and breeding of P. mume cultivars.

“…Plant floral fragrances are characterized by high diversity; even if the flower type and color are similar, the flower fragrance is not exactly the same [37,38]. Some scent substances contribute to the unique fragrance of a plant; for example, 3,5-dimethoxybenzene and 1,3,5-trimethoxybenzene (phenolic, spicy, earthy, and animalic notes) endow the tea-scent perfume to the Chinese rose [9]. At present, more than 2000 fragrance substances have been identified [39], among which terpenoids are the largest class of substances [40].…”

“…China is the distribution center of Rosa in the world [7], rich in Rosa varieties (approximately 90) which have unique characteristics, and plays an important role in the modern rose cultivation history. Ten of the 15 important parents of modern roses come from China [8,9], which provided favorable conditions for cultivating garden roses [10,11] containing recurrent flowering, high central flower shape, and tea aroma characteristics and other excellent varieties. The first hybrid tea rose in the world, named 'La France', has a typical tea flavor which comes from one of the important parents, a Chinese R. odorata ('Parks' Yellow Tea-scented China') [7,12].…”

“…However, SPME can maximally maintain the integrity and authenticity of the flora VOCs [20]. This method is simple, rapid, and effective, with a low detection threshold [21].Therefore, SPME is the best method to extract volatile organic compounds and has been widely used [9,22]. Gas chromatography-mass spectrometry (GC-MS) is currently the most commonly used method for the determination of volatile substances [23].…”

As the distribution center of Rosa in the world, China has abundant wild germplasm resources, which can contribute to the breeding of modern roses. To explore the potential value of wild roses distributed in the Sichuan–Tibet region, solid phase microextraction (SPME) and gas chromatography–mass spectrometry (GC–MS) were used to determine the volatile organic compounds (VOCs) in Rosa willmottiae flowers at three flowering stages (bud stage, initial flowering stage, full flowering stage). Meanwhile, we compared the VOCs of R. willmottiae with different phenotypes (double flowers and single flowers). A total of 74 volatile compounds were identified. The results show that the essential substances belong to alcohols and terpenoids. The main volatile organic compounds are 2-phenyl ethanol (20.49%), benzyl alcohol (10.69%), β-maaliene (8.66%), geranyl acetate (8.47%), and (+)-α-long pinene (6.127%). Different flowering stages had great influence on the volatile profile, from the bud stage to full flowering stage; the content of terpenoids released decreased by 6.17%, whereas alcohols and esters increased by 8.58% and 11.56%, respectively. The chemical diversity and the content of the main components with a different phenotype were not significantly different. Our result will provide a theoretical basis for the development and utilization of Rosa willmottiae in Sichuan and Tibet.

“…Gas recognition performance was improved by increasing the number of characteristic variables in the response matrix processed by the PCA algorithm. Three plant-based essential oils molecules with similar sizes and structures—phenethyl alcohol [ 37 ], acetophenone [ 38 ] and anethole [ 39 ]—were selected as target gases. Three kinds of polymers possessing different molecular structures and functional groups—Poly (acrylic acid) (PAA), Poly (methyl methacrylate) (PMMA) and Polydimethylsiloxane (PDMS)—were employed as sensing films.…”

The Surface-Enhanced Raman Scattering (SERS) technique is utilized to fabricate sensors for gas detection due to its rapid detection speed and high sensitivity. However, gases with similar molecular structures are difficult to directly discriminate using SERS gas sensors because there are characteristic peak overlaps in the Raman spectra. Here, we proposed a multiple SERS gas sensor matrix via a spin-coating functional polymer to enhance the gas recognition capability. Poly (acrylic acid) (PAA), Poly (methyl methacrylate) (PMMA) and Polydimethylsiloxane (PDMS) were employed to fabricate the polymer film. The high design flexibility of the two-layer film was realized by the layer-by-layer method with 2 one-layer films. The SERS gas sensor coated by different polymer films showed a distinct affinity to target gases. The principle component analysis (PCA) algorithm was used for the further clustering of gas molecules. Three target gases, phenethyl alcohol, acetophenone and anethole, were perfectly discriminated, as the characteristic variables in the response matrix constructed by the combination of gas responses obtained 3 one-layer and 3 two-layer film-coated sensors. This research provides a new SERS sensing approach for recognizing gases with similar molecular structures.
