L - (-) - Spectroscopic Analysis of Menthol Compounds Formed with Certain Dicarboxylic Acids

Abstract

Natural compounds isolated from plants have a high biological activity, and terpenoids and their derivatives occupy a special place among such compounds.

The healing properties of herbs are determined by their chemical composition, i.e. the presence of alkaloids, flavonoids, vitamins, carbohydrates and other substances. One such plant is the Menthapiperita plant, the monoterpene-menthol substance is the basis of the essential oil extracted from the surface of the plant. Peppermint oil is extracted from the leaves and other surface parts of the plant, and its composition consists of 50% menthol, 9% acetic acid and valeric acid menthol esters.

This paper provides information on some physicochemical properties of compounds of monoterpenoid menthol formed with some dicarboxylic acids. The results of the analysis of the chemical structure of the obtained compounds based on the results obtained by IR, Mass and Raman spectroscopy were presented.
