Abstract: The use of Xylopia frutescens extract as a C38 steel corrosion inhibitor in 1 M HCl solution was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. Potentiodynamic polarization curves indicated that Xylopia frutescens extract behaves as mixed-type inhibitor. Graphical methods are illustrated by synthetic data to determine the parameter of CPE (α Q). The adsorption of the extract constituents was further discussed in view of angmuir adsorption isotherm. The effect of temperature on the inhibition efficiency was investigated using EIS and potentiodynamic polarization. SEM and EDX observations confirmed the existence of protective inhibitor film on metal surface. © The Electrochemical Society.

Niamké, B. F., & Amusant, N. (2014). Déterminants biochimiques de la durabilité naturelle du bois de teck Recherche des composés phénoliques impliqués dans la durabilité naturelle du teck. Edition Universitaire Européenne.
Abstract: La durabilité du bois est une propriété très importante pour son usage futur. Chez le teck, cette propriété peut varier selon le génotype et les facteurs environnementaux mais aussi en fonction de la composition chimique du bois. Le présent document s’est attaché à rechercher les déterminants biochimiques de la durabilité naturelle chez le teck. Il ressort de cette étude que les formes osidiques stockées dans l’aubier sont transformées en extractibles de nature quinonique. Ces mécanismes de transformation pourraient indiquer le niveau de durabilité naturelle des espèces. Ainsi, les corrélations établies entre la durabilité naturelle et les teneurs en composés phénoliques ont permis d’identifier et de caractériser quelques traits de cette propriété. En outre, l’activité fongicide de ces composés phénoliques a été déterminée afin de s’assurer de leur implication dans la propriété de résistance du bois de teck. Ces nouvelles données contribueront à l’amélioration de la qualité du bois qui par ailleurs assure la pérennité des arbres.

Abstract: The implication of quinones in decay resistance of teak wood is controversial. To better understand the role of individual quinone in this property, we studied the correlations between this latter and the content of 2-(hydroxymethyl)anthraquinone, tectoquinone, anthraquinone-2-carboxylic acid, 1,4-naphthoquinone, lapachol and the new compound 4’,5’-dihydroxy-epiisocatalponol found in teak wood. Then, we studied the fungicidal activities of these quinones in comparison to acetone/water extracts from teak heartwood and sapwood and also with the commercial biocide tebuconazole. Broth dilution technique was used to assess the toxicity of these compounds against Trametes versicolor and Poria placenta. Decay resistance was measured according to current standards and individual quinones content were quantified by high performance liquid chromatography. High positive correlations were found between teak decay resistance and the content of 4’,5’-dihydroxy-epiisocatalponol, tectoquinone, 2-(hydroxymethyl)anthraquinone. Whereas no correlation was found with anthraquinone-2-carboxylic acid, lapachol and 1,4-naphthoquinone. Concerning the fungicidal activities of teak wood extractives, acetone/water heartwood extract was toxic against the two fungi while that of acetone/water sapwood was only fungistatic. 1,4-naphthoquinone and 4’,5’-dihydroxy-epiisocatalponol from the naphthoquinones family were fungicide. However, lapachol and all studied anthraquinones (2-(hydroxymethyl)anthraquinone, anthraquinone-2-carboxylic acid and tectoquinone) were fungistatic or not toxic. In the present study, 1,4-naphthoquinone was found the more toxic with a fungicidal activity 1000-times lower than that of the commercial biocide and over 2000-times lower than that of acetone/water heartwood extracts. These results show that decay resistance of teak wood could be mostly due to the content of naphthoquinone, particularly to that of 1,4-naphthoquinone indicating that it could be used as a potential wood preservative for lesser durable species.
