A characterization NMR of secondary metabolites from lichen Parmotrema praesorediosum

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The research study was carried out to extract, isolate and characterize the secondary metabolites of lichen Parmotrema praesorediosum. Most of the lichen samples were obtained from betel nut trees and needle flowers which were collected from 17 different places around UKM Bangi campus. Each lichen sample was dried before being grinded and extracted in methanol for nine days. This process was repeated three times at room temperature. Subsequently, the resulting residues were filtered to obtain the crude extracts and further analysed using Thin Layer Chromatography (TLC) and Vacuum Column Chromatography (VLC). In order to derive the pure compounds, the isolation step was proceeded using Radial Chromatography (RC). These isolated compounds were determined by Nuclear Magnetic Resonances (NMR) and identified as methyl haematomatte (1), methyl chlorohaematomatte (2) and methyl β-orsellinate (3).
