Abstract

In this study, the inhibition effect of Tamarix Boveana (TB) extract on Cu corrosion in 1 mol L–1 (HNO3 + H3PO4) mixture was studied. Electrochemical techniques such as (potentiodynamic polarization (PP), electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM)) and non-electrochemical technique such as mass loss were used. Results showed that TB extract has good inhibition efficiency (IE), follows Langmuir adsorption isotherm and all of the methods are in good agreement. The IE increased by increasing the concentration of the extract and decreased by increasing the temperature so, the extract adsorbed on Cu surface physically. The IE depends on the concentration of the extract and reaches 73.5% at 300 ppm of the extract. PP results revealed that the (TB) extract doings as mixed type one. Surface analysis revealed that the extract components are adsorbed on Cu surface forming a film. [ABSTRACT FROM AUTHOR]

2. Does Tamarix dalmatica (Tamaricaceae) occur in Spain?

Author

Subjects

Abstract

The presence of Tamarix dalmatica in the Iberian Peninsula, and its confusion in Spain with the native species T. boveana and T. africana, is discussed. A morphological comparison between these three species, and a critical study of the causes for the confusion between them, is presented. This includes an analysis of the variability in some morphological characters used for the identification of these species, together with clarifications of some discrepancies between the original descriptions and our observations of the type material. As a conclusion, T. dalmatica is excluded from the Iberian and Balearic floras.

3. Chemical composition and antimicrobial activity of volatile compounds of Tamarix boveana (Tamaricaceae)

Author

Saïdana, D., Mahjoub, M.A., Boussaada, O., Chriaa, J., Chéraif, I., Daami, M., Mighri, Z., and Helal, A.N.

Subjects
*ANTI-infective agents, *ESSENTIAL oils, *ANTIBACTERIAL agents, *FUNGUS-bacterium relationships
Abstract

Summary: The chemical composition of the Tamarix boveana volatile oils obtained from the whole aerial part, flowers, leaves and stems by steam distillation was analysed using gas chromatograph (GC)-flame ionization detectors (FID) and GC–MS. Sixty-two components were identified. Hexadecanoic acid (18.14%), docosane (13.34%), germacrene D (7.68%), fenchyl acetate (7.34%), Benzyl benzoate (4.11%) were found to be the major components in the whole aerial parts. This composition differed according to the tested part: 2.4 Nonadienal was the main compound in the flowers (12.13%) while germacrene D was the major component in leaves (31.43%) and hexadecanoic acid in the stems (13.94%). To evaluate in vitro antimicrobial activity, all volatile oils were tested against six Gram-positive and Gram-negative bacteria and four fungi. The T. boveana volatile oils exhibited an interesting antibacterial activity against all strains tested except Pseudomonas aeruginosa but no antifungal activity was detected.

As a conclusion, T. dalmatica is excluded from the Iberian and Balearic floras. Se discute la presencia de Tamarix dalmatica en la Península Ibérica e Islas Baleares. Se pone de manifiesto la frecuente confusión de esta especie, en el territorio peninsular, con las nativas T. boveana y T. africana. Se realiza una comparación morfológica entre las tres especies y un estudio crítico de las causas que han provocado dicha confusión. Así mismo, se discute la variabilidad existente en algunos caracteres morfológicos utilizados para la identificación de estas especies, así como algunas discrepancias entre las descripciones originales publicadas y el material tipo. Como conclusión se descarta la presencia de T. dalmatica en la flora ibero-balear. The FPU programme (Mº de Educación, Spain), project CGL2008-05056I+D+I (Mº de Educación y Ciencia, Spain) and complementary supporting funds ACIE10-01, ACIE11-05 (University of Alicante, Spain) made this research possible.
