Identification of the novel odor active compounds “p-menthane lactones” responsible for the characteristic aroma of fresh peppermint leaf was written by Shigeto, Atsushi;Wada, Atsushi;Kumazawa, Kenji. And the article was included in Bioscience, Biotechnology, and Biochemistry in 2020.Reference of 868-57-5 This article mentions the following:
The comparative aroma extract dilution anal. (cAEDA) applied to the volatile fractions of two types of fresh mint leaves (Peppermint and Spearmint) revealed 20 odor-active peaks with high FD factors (â?4). Among the perceived odorants, five “sweet/milky” and “caramel-like/spicy” notes showing high FD factors were characteristic for the peppermint aroma, and were identified as p-menthane lactone derivatives Especially, the three p-menthane lactone derivatives, “rel-(3S,3aS,6R,7aS)-dihydromintlactone, (3S,3aS,6R)-epoxymenthofurolactone, and 2E-ethylidene-5-methylcyclohexanone”, were newly identified compounds in the peppermint. The biosynthetic routes of the p-menthane lactone derivatives have been suggested to be closely related to menthofuran. Therefore, these findings strongly suggest the possibility that the biosynthetic pathway leading to the p-menthane lactone derivatives via menthofuran plays a significantly important role in the formation of the characteristic aroma of peppermint. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Reference of 868-57-5).
Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. 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.Reference of 868-57-5
