This study investigated the impact of storage duration on olive mill wastewater (OMW) quality and biological properties. Among two various olive varieties, Abani exhibited the highest phenolic compound concentration after 12 months of storage. Liquid chromatography-mass spectrometry (LC-MS) analysis identified 28 OMW constituents, with kampherol as the major one, and rosmarinic acid detected for the first time. Results showed significant differences in antioxidant and anti-inflammatory activities among samples. The inhibition of protein denaturation (IPD) test yielded the best value after 1 month for Abani OMW, while membrane-stabilizing potential (MSP) test values were highest after 12 months for the same variety. Anticoagulant activity, measured by activating partial thromboplastin time (APTT) and prothrombin time (PT), significantly varied with storage time, with the most favorable values found in Zlitni OMW immediately after olive oil extraction. These findings illuminate OMW changes over time, bearing significance for OMW management and potential applications.

“…Incubate the reaction medium at room temperature for 10 minutes. Measure the absorbance of the reaction mixture at 700 nm against a blank, which contains all reagents except FeCl3 (Gueboudji et al, 2022b). The same protocol is followed for the three standard antioxidants (Ascorbic acid, Trolox, and BHT).…”

Olive mill waste (OMW) is a by-product of the olive oil production process that has attracted increasing attention due to its rich composition of bioactive compounds. This chapter explores the extensive and diverse antioxidant and bioactive potential of OMW. OMW is a complex mixture comprising organic compounds, including phenolic compounds, flavonoids, polysaccharides, and various other valuable molecules. These compounds have demonstrated a wide range of applications, including their use as fertilizers, antioxidants, antifungal and antibacterial agents, cytoprotective agents, and stabilizing agents in food preservation. The chapter delves into the types of phenolic compounds found in OMW, providing detailed insights into their structures and functions. Additionally, it discusses the factors affecting the composition of OMW, such as the extraction process and processing conditions. Additionally, the chapter explores the growing interest in the health benefits associated with the consumption of bioactive compounds derived from OMW. These compounds have been linked to potential therapeutic properties, including antioxidant, anti-inflammatory, and anticancer effects. The exploration of OMW’s bioactive potential opens avenues for research and innovation, offering sustainable solutions for both waste management and the development of health-promoting products.

Several articles in the literature deal with and analyze components extracted from the olive tree, but these researches are mainly focused on the quality of olive oil and more precisely its volatile components, often related to their antioxidant properties, which denies other derivatives of the olive tree that are traditional sources of several healing broths. A thorough comparison of the richness of the different derivatives as well as the methods of extraction and identification will help to provide a useful decision-making tool. Olive tree derivatives were extracted in different ways to better understand the chemical composition of the Chemlali olive tree variety as well as to evaluate the efficiency of advanced extraction procedures. A comparison through the IC50 of the Chemlali variety with other olive cultivars was performed. It shows the richness of this variety in polyphenols. In addition, we present here a qualitative and quantitative table of basic chemicals for pharmacological use derived from olive oil, leaf, and bark that have been previously described in the literature. Diverse types and concentrations of phenolic compounds-an important class of natural antioxidants-can be found in different components of olives, including leaves, fruit, pits, seeds, bark, and paste. However, comprehensive studies are deficient in comparing the quantities extracted from these different sources. Indeed, this review attempt shows the diversity of Chemlali through the use of highvalue-added molecules (VAT), which can be categorized as diterpenes such as tyrosol and phytol, triterpenes such as squalene, as well as cinnamates.
