Essential oil of aerial parts Salvia aucheri Boiss. var. mesatlantica was obtained by hydrodistillation and analyzed GC GC/MS. The predominated camphor (49.59%). inhibitory effect this essential estimated on the corrosion steel in 0.5 M H2SO4 using electrochemical polarization weight loss measurements. rate is decreased presence natural oil. inhibition efficiency found to increase with content attain 86.12% at 2 g/L. Polarization curves revealed that S. acts as mixed type inhibitor a strong...
The essential oil from aerial parts of Mentha spicata L. an aromatic member the Lamiaceae family, collected "Tazouka" (Errachidia-Morocco), was obtained by hydrodistillation using Clevenger apparatus and analyzed GC GC/MS. constituents were identified their Mass spectra Retention indices. Forty one compounds consisting 91.90% total components obtained. Among those, Carvone (29.00%) Trans carveol (14.00%) major components. inhibitory effect this estimated on corrosion steel in 1M hydrochloric...
The objective of this research work is the study inhibitory effect Warionia saharea essential oil (WSEO) on corrosion mild steel (MS) in molar HCl solution, employing both experimental and theoretical methods. This (IE) has been evaluated by using a combination weight loss measurements (LW) various electrochemical methods, such as open circuit potential (OCP), potentiodynamic polarization (PDP) impedance spectroscopy (EIS) experiments. LW results indicated that IE increased with inhibitor...
The corrosion inhibition properties of three spiro-isoxazoline derivatives, namely 3,4-diphenyl-1,7-dioxa-2-azaspiro[4.4]non-2-en-6-one (DDA), 3-phenyl-4-(p-tolyl)-1,7-dioxa-2-azaspiro[4.4]non-2-en-6-one (PDA) and 4-(4-methoxyphenyl)-3-phenyl-1,7-dioxa-2-azaspiro[4.4]non-2-en-6-one (MDA) on carbon steel in 1.0 mol/L HCl acid medium were experimentally computationally investigated. experimental results showed that the inhibitory efficiency reached remarkable values 76.26, 80.31, 82.91%,...
Essential oil of leaves Asteriscus graveolens was obtained by hydrodistillation and analyzed GC, GC/MS 13C NMR. Twenty-seven compounds were identified amounting to 98.1% the total oil. This essential characterized having a high content oxygenated sesquiterpenes (93.3%) with 6-oxocyclonerolidol 19 (74.9%) 6-hydroxycyclonerolidol 23 (11.8%) are major components. The inhibition corrosion mild steel in sulphuric acid solution has been studied using weight loss measurements, electrochemical...
<title>Abstract</title> This study presents a comprehensive investigation of N-methyl-2-pyrrolidone (NMP) as corrosion inhibitor for carbon steel (C38) in 1.0 M HCl environment, using both theoretical and experimental approaches. To the best our knowledge, this is first time NMP has been studied its anticorrosive properties. Electrochemical tests, conducted with an SP150 potentiostat three-electrode system, revealed that effectively inhibits through cathodic protection. The adsorption onto...

Essential oil of aerial parts Pulicaria mauritanica was obtained by hydrodistillation and analyzed GC GC/MS. This tested as corrosion inhibitor mild steel in 0.5M H2SO4 using weight loss measurements, electrochemical polarization EIS methods. The analysis P. essential allowed the identification 25 components, which accounted for 94.3% total Carvotanacetone predominant compound constituting 87.3%. inhibitory effect this estimated on polarisation measurements. rate is decreased presence oil....
The essential oils of the aerial parts Asteriscus graveolens have been studied using GC and GC-MS. Twenty-eight compounds were identified in oil amounting to 94.9% total oil. part showed similar chromatographic profiles characterized by having a high content oxygenated sesquiterpenes with 6-oxocyclonerolidol (66.7% ±5.5) 6-hydroxycyclonerolidol (8.8% ±1.2) as major components. antifungal effect from A. leaves was evaluated vitro against three phytopathogenic fungi apples ( Alternaria sp.,...
This study was designed to examine the total phenolic and flavonoid levels antioxidant activities of essential oil (EO) various extracts obtained from fruits Ammodaucus leucotrichus using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. According results obtained, odorized exhibited stronger activity than desodorized extracts. The highest radical-scavenging shown by water soluble (OdMW) methanol extract (IC50 = 36.7 µg.ml−1), whereas EO showed weakest potential with an IC50 3326.7 µg.ml−1. As...
