Resumen
Olive leaves are generated in large quantities in olive oil and table olive factories. This waste is currently used for multiple purposes, one of them being the extraction of bioactive substances, in particular phenolic compounds. The aims of this study were (i) to obtain a new polyphenolic extract from potassium hydroxide (KOH) -treated olive leaves; and (ii) to reduce acrylamide formation in black olives by using this extract. The results showed that olive leaves and leafless branches of the Manzanilla cultivar treated with 10 g/L KOH provide a solution that, concentrated under vacuum, had &

Resumen
Ceylon olive (Elaeocarpus serratus L.) leaves have shown many pharmacological effects. Standardization of crude drug and extract needs to be conducted to assure the quality of the said material and further to support the pharmacological, pharmacokinetics, and toxicity effects. Standardization of Ceylon olive leaf extract is carried out to determine the standard parameters of crude drug and ethanolic extract of Ceylon olive leaves. Determination of the quality standard of crude drug and extract includes specific and non-specific parameters. The extract was obtained from a 70% ethanol maceration

Resumen
Background: There has been an increase in interest in studies for the extraction of biologically active compounds from natural sources during the past decade. The Oleaeuropaea L. tree, occasionally referred to as the olive, is one of the members of the Oleaceae family and is very significant historically and economically, particularly in Mediterranean countries. Olive leaves have a lofty phenolic compound, which offer them antioxidant properties and a decreased risk of illness. Aims: The aim of this study was to determine the bioactive compounds (polyphenol, flavonoids) and antioxidant activit

Resumen
Nowadays, olive leaf polyphenols have been at the center of scientific interest due to their beneficial effects on human health. The most abundant polyphenol in olive leaves is oleuropein. The biological properties of oleuropein are mainly due to the hydroxytyrosol moiety, a drastic catechol group, whose biological activity has been mentioned many times in the literature. Hence, in recent years, many nutritional supplements, food products, and cosmetics enriched in hydroxytyrosol have been developed and marketed, with unexpectedly positive results. However, the concentration levels of hydroxyt
