AB: | Fruit and vegetable simple and polyphenols are potent antioxidants. One of the most effective in terms of free radical scavenging is 3,4-dihydroxyphenyl ethanol or hydroxytyrosol (HT), a simple phenol found predominantly in Olea europea, or the olive plant. HT is most abundant in the aqueous fraction of olive pulp with trace amounts in the olive oil fraction and in the leaves. For these experiments, we evaluated the anti-inflammatory activity of olive vegetation water (OVW), which we showed previously to have potent antioxidant activity. Because some simple phenols and polyphenols with antioxidant activity have shown varying anti-inflammatory activities, we tested OVW and HT for their ability to inhibit the production of tumor necrosis factor-alpha (TNF-alpha), a pivotal cytokine in inflammation. In lipopolysaccharide (LPS)-treated BALB/c mice, a model system of inflammation, OVW at a dose of 125 mg/mouse (500 mg/kg) reduced serum TNF-alpha levels by 95%. In the human monocyte cell line, THP-1, OVW reduced LPS-induced TNF-alpha production by 50% at a concentration of 0.5 g/L (equivalent to approximately 0.03 g/L simple and polyphenols). OVW had no toxic effects in vitro or in vivo. When OVW was combined with glucosamine, a component of proteoglycans and glycoproteins that was shown to decrease inducible nitric oxide synthase production in cultured macrophage cells, the 2 compounds acted synergistically to reduce serum TNF-alpha levels in LPS-treated mice. These findings suggest that a combination of OVW and glucosamine may be an effective therapy for a variety of inflammatory processes, including rheumatoid and osteoarthritis.
