Leaves of Ligustrum vulgare are an alternative, sustainable source for oleuropein. Acidic hydrolysis of oleuropein furnishes hydroxytyrosol in good yield. This approach is one of the most convenient ways to access significant amounts of oleuropein as well as of hydroxytyrosol from plant material readily accessible all over the year and throughout Eurasia. Harvesting the leaves in winter doubles the amount of oleuropein that can be extracted from the plant material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
