ABSTRACT:
Olive mill wastewater (OMW), generated by the oil extraction industry, 
represents a severe environmental problem due to its highly polluting organic 
load arising from phenols with low biodegradability. However, with more than 
30 phenols, OMW is regarded as a potential source of natural antioxidants. 
This research aims to separate of phenolic acids from Syrian OMW. The phenols 
were extracted using different solvents: methanol, chloroform and 
ethylacetate. High performance liquid chromatography (HPLC) and 
spectrophotometric approaches were used to determine the phenols of OMW 
samples. Ethylacetate were the best solvent with phenols (493 mg/100g). The 
main isolated phenolic acids were p-hydroxybenzoic acid, ellagic acid, 
chlorogenic acid, caffeic acid, p-coumaric acid, sinapic acid, and ferulic 
acid.
