abstract
Olive mill wastewater (OMW), the effluents generated in the olive oil extraction
industry operating in three-phases mode, are phytotoxic mainly due to its high
phenolic content [1]. On the other hand, attending to the potential healthbenefits
of some of their phenolic compounds, OMW are now regarded as a
potent source of biophenols for food and pharmaceutical industries. An
important portion of the OMW biophenols include the secoiridoids found in
olive pulp and their derivatives formed along the olive oil extraction process
[2]. Still, due to the complex composition of OMW, many phenolic compounds
remain unknown. Their structural identification can encourage the search of
new bioactive compounds in OMW and contribute to further valorize this
waste.
