In present study, volatile components in petals of nine wild tree peony species were analyzed using a headspace solid-phase microextraction (SPME) technique coupled with gas chromatog.-mass spectrometry (GC-MS). A total of 124 volatile components were identified and clustered into five major chem. classes: terpenoids, alkanes, alcs., aldehydes, and ketones. Overall, combined with the sensory evaluation of nine wild tree peony species, Paeonia. ostii (P2) performed herbal and waxy attributes, mainly dominated by hexanal and pentadecane, resp. P rockii (P1), P qiui (P3), P jishanensis (P4), and P decomposita (P5) all possessed sweet attribute, which was pos. correlated with geraniol and citronellol. P delavayi (P9), P lutea (P7), P ludlowii (P8), and P potanini (P6) performed intense floral attribute dominated by linalool and trans-linalool oxide. Moreover, the results of principal component anal. (PCA) and hierarchical clustering anal. (HCA) showed P decomposita (P5), P qiui (P3), P rockii (P1), P jishanensis (P4), and P ostii (P2) in the Subsect. Vagiatae were mixed to form one cluster while P lutea (P7), P delavayi (P9), P ludlowii (P8), and P potanini (P6) in the Subsect. Delavayanae formed the other cluster. In terms of geog. distribution, the two clusters are consistent with the distribution of wild tree peony species. In the experiment, the researchers used many compounds, for example, Ethyl 2-hydroxybenzoate (cas: 118-61-6COA of Formula: C9H10O3).
Ethyl 2-hydroxybenzoate (cas: 118-61-6) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.COA of Formula: C9H10O3
