Abstract

Research on the isolation of anacardic acid compounds from cashew nut shells has been carried out. This study aims to develop a method of isolating anacardic acid compounds from cashew nut shells in an easier way but still produces pure compounds. In this study, isolation and identification of anacardic acid compounds contained in CNSL were carried out. The results of anacardic acid isolation contained in CNSL form a thick brown extract with a characteristic dark odor. Anacardic acid was isolated using a maceration method using methanol as a solvent. The results of the isolation of anacardic acid compounds were then tested for purity using a thin layer chromatography test (TLC) using an eluent or a mobile phase of methanol: chloroform. Furthermore, anacardic acid compounds were identified using IR spectroscopy and UV-vis spectroscopy. This identification was carried out to prove that the compound obtained was indeed an anacardic acid compound. The identification results found that the compound isolated in this study was indeed an anacardic acid compound. It can be compared with the structure of existing anacardic acid compounds.

Summary

INTRODUCTION

Cashew (Anacardiumoccidentale) plant is one of the plantation commodities that has a high economic value. Most are still waste, burned, or thrown away as rubbish This cashew nutshell is around 70% of the cashew nut shells (unpeeled cashew), and it is estimated that the amount of cashew shells removed is 100 thousand tons. Cashew nut shell oil contains natural phenol characterized by aromatic rings that bind to the OH group. They consist of anacardic acid, cardanol, cardols, and methyl cardols with a composition of anacardic acid that can reach 70%, cardanol 5%, cardanol 18%, and methyl cardol [4]. Anacardic acid has a high economic value Based on this background, researchers intend to develop methods of isolating anacardic acid compounds from cashew nut shells in an easier way but still producing compounds that remain pure. Anacardic acid compounds obtained later were purified by thin-layer chromatography (TLC) and identified using IR and UV-vis spectrophotometers
