dc.description.abstractAloe vera (Aloe barbadensis Mill.) is a succulent plant species cultivated worldwide for its jelly-like parenchyma that is used by cosmetic, pharmaceutical and nutraceutical industries. This gel fillet is found protected by a thick layer (green rind) that constitutes 20-30% of the whole leaf weight [1], which is often discarded as waste (Figure 1). However, this biowaste can be valorised as a source of high added-value phenolic compounds [2]. Today, the principles of green chemistry have been introduced into extraction schemes with the aim of making processes more sustainable. Some studies have also shown that polyols in aqueous solution may constitute a very suitable extraction medium for polyphenol recovery [3]. Therefore, this study was carried out to characterize the phenolic profile of Aloe vera rind, evaluate antioxidant properties of the obtained extracts, and investigate the suitability of propylene glycol-water mixtures for extracting these bioactive phenolic compounds.pt_PT
