Obtaining bioactive compounds from pomegranate peel waste

Abstract

The research work shows the advantages of recycling pomegranate peels, which are considered environmental waste. The possibility of obtaining valuable bioactive substances from them has been shown. The substances obtained during extraction are biologically active compounds with a wide range of applications. Ethyl acetate, which is widely used in the food industry, was chosen for the extraction process of pomegranate peels. The extraction process was carried out by the Soxhlet method at 60-77C. After removing the solvent from the obtained extract, a dark brown resin was obtained. The solubility of pomegranate peel in ethyl acetate was 64.7% according to the results. The main purpose of this work is to identify the functional groups belonging to the bioactive compounds in the composition of the ethyl extract of pomegranate peel. The ethyl acetate extract of pomegranate peel was studied using an IR-FURYE spectrometer. In the spectrum, 4 peaks corresponding to the wavelength of the aliphatic CH bond in alkyl groups were observed in the region of 2984.41 - 2878.28 cm-1. The absorption band at 1738.58 cm-1 was attributed to the broad OH group in carboxylic acids. Keywords: biomass, recycling, pomegranate peel, extraction, ethyl acetate, IR spectra
