Extraction of Phenol Compounds in the Liquid Smoke by Pyrolysis of Oil Palm Fronds

Abstract

The total content of phenol compounds present in the liquid smoke can be extracted either by using polar or non-polar solvents. Polar and non-polar
solvents are often used to extract phenol compounds from plants. Extraction of phenol compounds was performed by using ethyl acetate and hexane
solvents at 40° C, 55° C and 70° C within 60, 120, and 180 minutes. The highest total content of phenol compounds is obtained through extraction
process at 70o C within 180 minutes using ethyl acetate solvent, which is 103,394 mg/g. While, the lowest one is obtained through extraction process
at 40o C within 60 minutes using hexane solvent, which is 13,697 mg/g. The phenol compounds obtained are syringol and guiaicol compounds
using ethyl acetate solvent within 180 minutes, at the temperature of 70o C, which is 5,44% and 3,97%.
