Diversity in principal constituents of plants with a lemony scent and the predominance of citral was written by Hirai, Miho;Ota, Yue;Ito, Michiho. And the article was included in Journal of Natural Medicines in 2022.SDS of cas: 105-87-3 This article mentions the following:
In this study, we extracted essential oils from four species of plants with lemony scents (Melissa officinalis L., Aloysia citriodora Palau (= Lippia citriodora (Palau) Kunth), Thymus x citriodorus, Perilla citriodora (Makino) Nakai). We then examined the components of extracts using gas chromatog. (GC) and GC-mass spectrometry (GC-MS). A comparison of components indicated that the largest proportions of essential oils were caryophyllene (25%) in M. officinalis, geraniol (50%) in T. citriodorus, and citral (61 and 82%) in A. citriodora and P. citriodora. Moreover, we used a sensory evaluation method using dilute aqueous solutions of extract components, citral, linalool, d-limonene, and geraniol, to select the mixture with a flavor that mostly resembled lemon. The participants in the study felt that an aqueous citral solution flavored more like lemon than aqueous d-limonene. Furthermore, an open field study of sedative effects of citral and d-limonene, when inhaled, on mice demonstrated that citral exhibited a sedative effect at a lower concentration than that of d-limonene. In the experiment, the researchers used many compounds, for example, (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3SDS of cas: 105-87-3).
(E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.SDS of cas: 105-87-3
