Propolis is a natural resinous substance collected by honeybees from buds and exudates of trees and is used by bees as a glue, general-purpose sealer and draught extruder for beehives. Known in folk medicine since ancient times, propolis has attracted much attention in recent years as a useful ingredient applied in medicine, domestic products and food products since it possesses various biological properties including antimicrobial, antioxidative and antiulcer properties. In this project, accelerated solvent extraction (ASE) was used to extract the different chemicals from a bee propolis sample. In addition different extraction methods were employed in the extraction of active compounds from the same bee propolis sample to compare their efficiency. The methods employed are soaking method, Soxhlet method, ultrasonic method and microwave method. The efficiency of the methods was determined based on the amount of materials extracted as determined by gas chromatography-mass spectrometry (GC-MS) and spectroscopic methods such as absorbance and fluorescence. Results show that samples obtained from ASE give similar yields similar to those obtained with ultrasonic and microwave methods.
