Abstract


Phenolic compounds are well-known phytochemicals found in all plants. They can be broadly divided into non-soluble compounds such as condensed tannins, lignin, and cell-wall bounded hydroxycinammic acid, and soluble phenolics such as phenolic acids, phenylpropanoids, flavonoids and quinones. In this work the extraction of total phenolic compounds (TPC) from LebaneseEryngiumcreticum was performed by two techniques: Conventional such as maceration, reflux and soxhlet extraction, and non-conventional extraction like microwave assisted extraction using ethanol as a solvent. The results shows that among the conventional extraction techniques reflux and Soxhlet techniques gave approximately the same yield of 687.8 mg and 685.23 mg respectively higher than that obtained by maceration technique (410.93 mg), however, Microwave assisted extraction gave the highest yield among both the conventional and non-conventional extraction techniques (950 mg).
