Characterization of the essential oil content of lemon (Citrus limon burm f.) peel and the active component of the cohobation waste

Abstract

Abstract Lemon (Citrus limon burm f.) peel is a waste from processing lemons that has not been utilized optimally. One effort to utilize lemon peel waste is by extracting essential oils. In the process of extracting essential oils of lemon peel, a waste by-product will be produced in the form of solid waste (cohobation waste). In order to increase the economic value of lemon peel, it is necessary to evaluate the content of active components in the cohobation waste of the lemon peel extraction process. This study aims to examine the essential oil components in lemon peel and the active components contained in the cohobation waste resulted from the extraction process. The essential oil extraction method used was cohobation. The testing method used was the Gas Chromatography Mass Spectrometry (GCMS). The results showed that the essential oil components extracted from lemon peel were: d-limonene (79.38%), citral (5.98%), neral (3.62%), 3-cyclohexene-1-methanol, α.,α.4-trimethyl-3-cyclohexene-1-methanol (2.94%), linalool (2%), β-myrcene (1.18%), and p-mentha-1,5-dien-8-ol (1.85%). While the results of the cohobation waste test contained various active components, such as: 9,12 octadecadienoic acid (20.66%), g-sitosterol (11.47%), hexadecanoic acid (9.85%), β-bisabolene (9.45%), β-fenchol (7.57%), α-bergamotene (5.47%), vitamin E (2.57%), and campesterol (2.24%).
