the antioxidant properties and total phenols’ content of 80% methanol, acetone and water extracts of olive leaves procured through microwave assisted extraction (mae) were examined. two varieties of olive namely: cronaiky and roghani were the ones studied. various experimental models were employed for antioxidant activity evaluation of the extracts. the results revealed the highest phenolic con...

The aim of this study was investigation of influence of different extracts addition on total phenols, anthocyanin content, antioxidant activity and percent of polymeric colour of blackberry juice during storage of 52 days at 4 °C. Anthocyanin content of control sample (blackberry juice without extracts addition) was 149.91 mg/L. Samples with addition of extracts (olive leaf, pine bark PE 5:1, p...

We studied 92 patients with allergic rhinitis in Syodoshima, Japan, during the pollen season between April and June to evaluate the cross-reactivity to different antigens, including pollen from the olive tree (Olea europaea) and orchard grass (Dactylis glomerata). Olive tree pollen was present in the atmosphere for 23 days, from May 19 to June 12, 1994. Specific IgE antibodies for olive tree po...

The present study was conducted to evaluate the hepatoprotective activity of ethanolic leaf extract of Couroupita guianensis against CCL4 induced liver damage in rats. Anti-oxidant activity was evaluated by DPPH (2, 2-diphenyl-1-picrylhydrazyl) and hydrogen peroxide scavenging. Ascorbic acid was used as the standard antioxidants for comparison. Healthy male Wistar albino rats of either sex (150...

Extensive efforts are exerted looking for safe and effective chemotherapy for hepatocellular carcinoma (HCC). Specific and sensitive early biomarkers for HCC still in query. Present work to study proteolytic activity and lysosomal membrane integrity by hepatocarcinogen, trichloroacetic acid (TCA), in Wistar rats against aqueous olive leaf extract (AOLE).TCA showed neoplastic changes as oval- or...

Plant biophenols have been shown to be effective in the modulation of Alzheimer's disease (AD) pathology resulting from free radical-induced oxidative stress and imbalance of the redox chemistry of transition metal ions (e.g., iron and copper). On the basis of earlier reported pharmacological activities, olive biophenols would also be expected to have anti-Alzheimer's activity. In the present s...

The production of olive oil generates massive quantities of by-product called olive mill wastewater (OMWW). The uncontrolled disposal of OMWW poses serious environmental problems. The OMWW effluent is rich in several polyphenolic compounds. Liquid-liquid extraction of OMWW using ethyl acetate solvent was used to enrich phenolic compounds under investigation. Total phenolic and flavonoid content...

BACKGROUND AND PURPOSE Pistacia atlantica, which belongs to the Anacardiaceae family, grows in the Zagrossian region of Iran. The aim of this study was to evaluate the antifungal properties of Pistacia atlantica and olive leaf extracts against different fungal species. MATERIALS AND METHODS In this study, we assessed the activities of olive leaf extracts and Pistacia atlantica leaf and fruit ...
