Anticorrosion action of the olive leaf compounds extracted under optimal parameters as determined with experimental design

نویسندگان

چکیده

In this study, an agricultural waste product was used to prepare a green corrosion inhibitor based on olive leaves (Olea europaea var. syslvestris). Firstly, optimization study of antioxidant activity O. monitored by the DPPH free radical trapping method, carried out using full factorial design. second step, extract obtained under optimal conditions tested as for steel in 0.5 mol dm-3 HCl, gravimetric and electrochemical methods. The results various techniques showed that acted mixed-type inhibitor. adsorption spontaneous (?Gads = ?12.443 kJ mol-1), through mechanism physical adsorption, it obeyed Langmuir isotherm. highest inhibition efficiency 92 % 2.8 10-3 g cm-3of inhibitor, measured method.

Antifungal Activity of Phenolic Compounds Extracted from Dried Olive Pomace

The antifungal activity of phenolic compounds extracted from olive pomace against Alternaria solani, Botrytis cinerea and Fusarium culmorum was investigated. Olive pomace, a by-product of olive oil production, was used as a source of phenolic compounds. The extracted phenolics were added to a medium to reach phenol concentration of 0.1 and 0.2 % (w/v) and tested for their antifungal activity ag...

Development of Phenol-Enriched Olive Oil with Phenolic Compounds Extracted from Wastewater Produced by Physical Refining

While in the last few years the use of olive cake and mill wastewater as natural sources of phenolic compounds has been widely considered and several studies have focused on the development of new extraction methods and on the production of functional foods enriched with natural antioxidants, no data has been available on the production of a phenol-enriched refined olive oil with its own phenol...

Optimization of Phenolic compounds Extraction from Olive Leaves using Experimental Design Methodology

Olive products, such as oils, olives and leaves infusions, have been used in the past to treat many health problems. This study aims to develop a methodology for maximizing the efficiency of extraction of polyphenols from olive leaves. For this purpose, two experimental design approaches (a central composite design (CCD) and a mixture design) have been used. The optimal extraction parameters ob...
