Abstract |
Ce travail porte sur l’inhibition de l’acier C38 en milieu acide HCl 1M par les extraits alcaloïdiques issus de 2 plantes : Aspidosperma album et Geissospermum laeve. Biodégradables et respectueux de l’environnement, les alcaloïdes pourraient être utilisés temporairement pour prévenir la corrosion de l’acier C38 avec des taux d’inhibition supérieurs à ceux décrits dans la littérature. Dans la première partie du travail, l’influence de la concentration, du temps d’immersion et de la température sur les processus de corrosion de l’acier C38 en milieu HCl 1M en absence et en présence d’inhibiteur a été étudiée par des mesures électrochimiques : courbes de polarisation et spectroscopie d’impédance électrochimique. Les analyses de surface effectuées par microscopie électronique à balayage montrent la présence d’une couche constituée d’un mélange d’oxyde de fer incorporant les alcaloïdes et qui conduit à la diminution de la vitesse de corrosion. La deuxième partie de ce travail a été consacrée à l’isolement des alcaloïdes des deux extraits afin de déterminer le ou les alcaloïdes responsables de l’activité inhibitrice et ainsi remonter aux mécanismes d’adsorption. Il a été montré que l’alcaloïde majoritaire des extraits est responsable de l’inhibition. |

Abstract |
Aniba rosaeodora, is a slow growing evergreens of the Lauraceae family which are indigenous over a wide range of the Greater Amazon Region (the Guianas and Venezuela, Brazilian Amazon…). The essential oil obtained from the wood has a characteristic aroma and is a long-established ingredient in the more expensive perfumes. Around the olfactive characteristic of the essential oil is due to the presence of levogyre linalol. The steam distilled wood oil is obtained in a yield ranging around 1% and up to 90% of the oil consists of optically active linalol. This work is focused on the valorization of steam distillated sawdust, waste obtained from extraction of essential oil. After steam distillation, the sawdust was extracted by ethyl acetate and methanolic solvents and the antifungal activity was evaluated against basidomycetes fungi. The both extracts were active in vitro against white and brown rot fungi and allowed to propose these extractives as wood preservative agent. |

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. |

Abstract |
The variation of a lesser-used species, Eperua grandiflora attacked by brown and white rot has been examined. Trees of this specie showed differences in their behaviour against the type of rot used and also showed evidence of intra and inter tree variation. The “tree” effect is very significant concerning natural resistance. In the same way, there is variation of durability observed according to radial and vertical position in the stem. Although the vertical effect is less significant from practises point of view. |
