Olive oil, a major feature of the Mediterranean diet, is an important source of phenolic compounds. Poliphenols are associated with inhibition of several pathological processes, including cancer. Soluble phenols are contained in the aqueous part of olive and are discarded during oil production in the ‘olive mill wastewaters’. Here we investigated the properties of a purified extract of olive mill wastewaters, named A009, as potential anti-angiogenic compound. While the strong anti-oxidant activity of olive derived phenolic compounds has been well characterized, little is known about their anti-angiogenic properties. We investigated effects of A009 on endothelial cell morphogenesis, proliferation, migration and apoptosis, comparing the results obtained with the activity of a well-characterized olive oil phenol, Hydroxytyrosol (HT). Further, we tested the effects of A009 and HT in an in vivo angiogenesis assay. We found that A009 exerted strong anti-angiogenic effects both in vitro and in vivo, and that the complex natural purified extract has stronger anti-angiogenic potential when compared to the same concentrations of HT in most of the assays performed. These data demonstrate that a novel purified, phenols enriched, extract with anti-angiogenic, and angiopreventive potential can be obtained from olive oil mill waste material, recovering useful products from an agricultural waste.
