ABSTRACT Background- Notwithstanding the way that olive fruits polyphenols and olive leafs polyphenols have been known for their natural anti-inflammatory effect in the Mediterranean countries, there is little deep scientific study to confirm these benefits. Background- Notwithstanding the way that olive fruits polyphenols and olive leafs polyphenols have been known for their natural anti-inflammatory effect in the Mediterranean countries, there is little deep scientific study to confirm these benefits. Objective- To assess the effect of rich-polyphenols olive tree powder (made of leafs, baby leafs, olive fruit and olive oil) made from olive trees planted in the middle of a rocky desert on inflammatory process and pain intensity, a randomized, double-blinded, placebo-controlled trial was conducted on human subjects with rheumatoid arthritis (RA). Methods- Seventy-nine RA patients were randomized to get either 1 g per day of olive tree powder or 1 g of placebo powder during 9 weeks. Laboratory analysis, questionnaires administration, pain intensity, disease activity score, and inflammatory biomarkers were determined at the baseline and at the end of the trial. Results- Good compliance (over 95%) with the treatment was observed, without any side effect or study intervention adverse. Significant decrease in disease activity score has shown at the end of intervention within the treated group, and between groups (P<0.0001). Compared with the placebo group, inflammatory biomarkers decreased significantly in treated participants (P<0.0001). Here are the changes noticed from baseline in treated group were -1.25 mg/L (CI, -1.75 to -0.75), -2.09 pg/mL (CI, -2.63 to -1.54), -0.82 pg/mL (CI, -1.14 to -0.49) and -1769 pg/mL (CI, -2254 to -1283) for hs-CRP, IL-6, TNF-α and PGE2 respectively. Additionally, it is important to note that pain relief and global participants satisfaction increased significantly (P<0.0001) after 9 weeks of olive tree powder supplementation. Conclusion- A net improvement in circulating inflammatory markers, disease activity, and pain intensity was observed in RA patients allocated to rich-polyphenols olive tree powder food supplement.

Displayed Title Goes Here strong>ABSTRACT Objectif- The aim of this study was the in vivo evaluation of analgesic and anti-inflammatory effect of an olive tree extract with high polyphenols content. Methods- This olive tree extract was obtained from Moroccan olive fruits and leaves using an eco-extraction free of chemical solvents and toxic additives. Antiinflammatory activity was evaluated using carrageenan and histamine-induced paw edema methods. Analgesic activity of the olive tree extract was estimated against a hot plate, acetic acid induced writhing and formalin tests. Results- The extracts showed significant antiinflammatory and analgesic activities with a dosedependent manner. Anti-inflammatory activity of olive tree extract at 250 and 500 mg/kg doses was more important compared to the used standard drugs (p<0.05), in both carrageenan and histamine-induced paw edema tests. In analgesic assays, results showed that 500 mg/kg dose of olive tree extract has a significant analgesic effect through both peripheral and central mechanisms. Conclusion- Our findings suggest that olive tree extract is safe and has potential anti-inflammatory and analgesic activities, which promote this use as a food supplement against pain and inflammation related to inflammatory diseases.

Displayed Title Goes Here ABSTRACT Objective- The aim of the present study was to determine the effects of an olive tree extract with high polyphenols content on blood glucose level and other related parameters in streptozotocin-induced diabetic rats. Methods- Diabetes was induced in rats by intraperitoneal injection of streptozotocin (55 mg/kg bw). 72h after injection, rats with fasting blood glucose higher than 2 g/l were used for the experiments. Olive tree extract was administered for 28 d and blood glucose level was measured every 4 d. Total cholesterol, triglycerides, HDL-cholesterol, creatinine, urea, total protein, uric acid, aspartate aminotransferase and alanine aminotransferase Results- The oral administration of olive tree extract contributes to blood glucose level decreasing in diabetic rats group, which was significantly lower at 4th week compared to the diabetic control rats. Moreover, supplementation by olive tree extract decreased significantly (p<0.05) the values of total cholesterol, triglycerides, HDL-cholesterol, creatinine, urea, total protein, uric acid, aspartate aminotransferase and alanine aminotransferase resulting from damage caused by streptozotocin treatment. Beside this, significant reduce (p<0.05) in heart disease risk ratio was observed for treated group (4.1±0.14) compared to untreated group (7.64±0.36), which was quite similar to normal rats (4.50±0.36). Studied olive tree extract effects were similar to those of glibenclamide, a well-known antidiabetic drug. Conclusion- Results herein obtained reveal the hypoglycemic effect of this olive tree extract, suggesting his potential use as a natural antidiabetic agent.

waste could be a promising source. In our work, we have prepared an olive tree extract from this waste, our extract contains 148 g/l of polyphenols, 8.4 g/l of flavonoids and 39.11 g/l of o-diphenols. Polyphenols, major natural antioxidants play a key role in hundreds biological reactions. The antioxidant activity test revealed great antioxidant potential of our extract with high ORAC value 3 848 100 μmol Te/kg. The present work has as objective to evaluate the antimicrobial activity. The olive tree extract showed broad- spectrum antibacterial activity against Escherichia coli, Escherichia coli TG1, Escherichia
coli DH5α, Staphylococcus aureus, Bacillus cereus, Bacillus cereus MED5 and Streptococcus agalactiae. While pure phenolic compounds (caffeic acid, ascorbic
acid and quercetin) showed more limited activity. The antifungal effect of the olive tree extract exceed the antibiotics at a concentration of 3 mg/disc (p<0.05). Industrial technology can therefore exploit this extract, rich in polyphenols, in order to use instead of a synthetic antioxidants and antibiotics that could be dangerous. This would lead Morocco to enhance the olive harvest waste as an important economic source.

activities. The in vitro cytotoxic activity of a crude olive tree extract and his major constitutive components has been evaluated against human KB, HL60 cancer cell lines using MTS and flow cytometry. ROS production was estimated with the DCFH- DA assay. Antiangiogenic activity was evaluated in vitro on endothelial cells tube formation and the pro-angiogenic factor expression was quantified using qRT-PCR. In vitro cellular assays have demonstrated the cytotoxic effect of the crude olive tree extract. This extract reduces significantly (p<0.05) ROS produced in cells exposed to oxidative stress. Beside this, olive tree extract has demonstrated a strong anti-angiogenic activity, which was correlated with a significant decrease (p<0.05) in VEGF, angiopoietin and HIF1α expression. Basically, the evaluation of anti- proliferative, antioxidant and antiangiogenic activities could be the first step to formulate an efficient pharmaceutical product with preventive and/ or curative properties against cancer.

Displayed Title Goes Here A-8-week randomized, double-blind, placebo-controlled clinical trial Ghanam Jamal, Laaboudi W and Benlemlih M* ABSTRACT Olive tree polyphenols have been known as natural anti-inflammatory agents. The aim of the current clinical trial was to assess the therapeutic effect of an olive tree extract with high polyphenols content on inflammatory processand pain intensity in rheumatoid arthritis (RA) patients. This is a randomized, double-blind, placebo-controlled clinical trial. Ninety RA patients were randomized into two groups; treated group received a daily dose of 3 g of olive extract (6 capsules, 500 mg each) during 8 weeks, while patients in placebo group received capsules with maltodextrin. Laboratory analysis, questionnaires administration, pain intensity, and inflammatory biomarkers were determined at the baseline and the end of the trial. Doctors assessed potential adverse effects of olive tree extract through the period of study. Significant decrease in disease activity score has shown at the end of intervention in the treated group and between groups (P<0.0001). Compared to the placebo group, inflammatory biomarkers decreased significantly in treated participants (P<0.0001). The changes from baseline in treated group were -1.37 mg/L
