Abstract The release of aqueous residues generated by the extraction process of essential oils presents a real risk of environmental pollution. This work aims to reduce this risk and produce value-added materials. The aqueous residue of Dittrichia graveolens (D. graveolens) hydrodistillation has been reused in two valorization ways: 1/ in the ecological dyeing. 2/ in biological field. First, a phytochemical study of the aqueous residue was carried out by determining the ployphenols and flavonoids content and high performance liquid chromatography (HPLC) analysis. Second, the eco-dyeing process with the aqueous residue was performed on the polyamide fabric, the process was optimized by the surface response methodology using Minitab software and was evaluated by the fastness tests for the optimal conditions. Third, the aqueous residue was assessed for its biological activities. Promising coloring power and biological potential of the aqueous residue showed that this last could be an important source for developing environmentally friendly natural dyes and bioactive products.

Experimental studies have provided convincing evidence that food bioactive compounds (FBCs) have a positive biological impact on human health, exerting protective effects against non-communicable diseases (NCD) including cancer and cardiovascular (CVDs), metabolic, and neurodegenerative disorders (NDDs). These benefits have been associated with the presence of secondary metabolites, namely polyphenols, glucosinolates, carotenoids, terpenoids, alkaloids, saponins, vitamins, and fibres, among others, derived from their antioxidant, antiatherogenic, anti-inflammatory, antimicrobial, antithrombotic, cardioprotective, and vasodilator properties. Polyphenols as one of the most abundant classes of bioactive compounds present in plant-based foods emerge as a promising approach for the development of efficacious preventive agents against NCDs with reduced side effects. The aim of this review is to present comprehensive and deep insights into the potential of polyphenols, from their chemical structure classification and biosynthesis to preventive effects on NCDs, namely cancer, CVDs, and NDDS. The challenge of polyphenols bioavailability and bioaccessibility will be explored in addition to useful industrial and environmental applications. Advanced and emerging extraction techniques will be highlighted and the high-resolution analytical techniques used for FBCs characterization, identification, and quantification will be considered.
