“…neoformans and dermatophyte ( Table 1). The high amounts of carvacrol in Portuguese L. multifida EOs are in accordance to those reported from Moroccan [25,48], and Algerian samples [49], nevertheless they must be considered different since cisβ-ocimene (2) also occurs in relatively high amounts, not observed for the Moroccan and Algerian samples. According to Khadir et al [50] and Messaoud et al [51], the EOs obtained from L. multifida collected in several places of Algeria or Tunisia, respectively, were predominantly constituted of carvacrol (3) and β-bisabolene (4).…”

“…Lavandula multifida (fern leaf lavender, Egyptian lavender) is a species of the section Pterostoechas occurring commonly along the Mediterranean coast (Egypt, Tunisia, Morocco, Algeria, Spain, Portugal). In Italy, the plant has been found in the hot and arid climatic conditions of Calabria and Sicily [22,23], whereas in Tunisia the plant can be found in upper semi-arid bioclimates, particularly in open calcareous garrigues [24]; and in Morocco it also grows on calcareous soils and on the borders of rivers of temporary drainage, between 800 and 2000 m altitude [25]. In Portugal, L. multifida grows in the southern region (Sesimbra, Arrábida and Mértola) [23].…”

Spontaneous lavender growing in uncultivated fields in Portugal have been used in traditional medicine for internal and external uses. The essential oils (EOs) of Lavandula stoechas subsp. luisieri are characterized by the presence of trans-α-necrodyl acetate and trans-necrodol. These EOs are able to prevent the generation and deposition of neurotoxic β-amyloid peptide in Alzheimer’s disease. The EOs also present antibacterial, anti-fungal, anti-Leishmania, antioxidant, anti-inflammatory and antifeedant effects. In the case of hydrodistillation, the predominant compound of Lavandula viridis EO was 1,8-cineole, nevertheless in the case of supercritical fluid extraction, the main constituent was camphor. In in vitro shoots EOs, 1,8-cineole and α-pinene were the most important compounds. The EOs presented anti-fungal activity particularly against Cryptococcus neoformans and dermatophytes. The antioxidant and anti-protozoal activities of L. viridis EOs were lower than L. stoechas subsp. luisieri EOs, with hydrodistillation being the best method for obtaining samples with higher antioxidant and anti-acetylcholinesterase activities. The presence of fenchone, 1,8-cineole and camphor was a common trace of the Lavandula pedunculata subsp. pedunculata EOs and in in vitro axillary shoots EOs. Lavandula pedunculata subsp. lusitanica EOs were predominantly constituted of fenchone and camphor. The antioxidant activity of L. pedunculata subsp. lusitanica EOs was poorer than other Lavandula EOs from Portugal.

“…More recently, Lavender oil has been found to be not harmful to the environment as corrosion inhibitor, Halambek et al [17] have carried out a study on the influence of Lavandula angustifolia L. on corrosion of Al-3 Mg alloy in 3% NaCl solution, the results showed an efficiency of 99% for a concentration of 20 ppm at 25 °C. The study by Znini et al [18] on the uses of Lavandula multifida L. oil as a corrosion inhibitor in 0.5 M H 2 SO 4 medium, showed that the oil exhibited a high inhibition efficiency of 72.2% at 2 g/L of oil at 25 °C, the usage of L. stoechas oil, abstracted from leaves as corrosion inhibitor of stainless steel in H 3 PO 4 solution was elaborated by Boudalia et al [19]. The inhibitory efficiency was 87.3% at 1.2 g/L at 25 °C.…”

The current study was designed to give more knowledge and helping to exploit the leaves of the plants L. stoechas collected in Tlemcen region in the west of Algeria by determining the anti-corrosive activity of its essential oil. The inhibitory efficiency of the essential oil of the plant obtained by hydrodistillation and characterized by GC and GC/MS was studied using gravimetric and electrochemical methods (polarization curves and electrochemical impedance). The effect of temperature on the corrosion behavior of the steel and the inhibitory efficiency was studied in a temperature range of 303-323 K at 2 g/L. The surface morphology of the samples immersed in 1 M HCl for 24 h, before and after adding inhibitor at (2 g/L at 30 °C) was analyzed by scanning electron microscope (SEM) Quanta 250 with tungsten filament from the company FEI. Results show that the addition of the essential oil of the plant to the medium induces a diminish in the rate of corrosion and augmentation in the inhibitory efficiency of the oil. We established that the inhibition efficiency increase with concentration of the essential oil of lavender to attain 76.19% at 2 g/L. Polarization curves revealed that lavender oil react as a mixed-type inhibitor. EIS spectra exhibit one capacitive loop and confirm the inhibitive ability, and the changes in impedance parameters were indicative of adsorption of essential oil of lavender on the metal surface. The thermodynamic parameters indicate that the adsorption of the molecules of the oil takes place according to the Langmuir isotherm in the corrosive medium studied and that they are physisorbed on the metal surface. The analysis of the surface by electron microscopy demonstrates the absence of surface attack patterns in the presence of the oil. The results obtained from different tested techniques were in good agreement.

The essential oil of Santolina pectinata aerial parts (SP oil) was extracted by hydrodistillation and analyzed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC/MS). 34 components were identified, accounting 59.4% of the total oil, which (Z)-heptadeca-10,16-dien-7-one (ZHD) was the major component with 28 % of the oil. The protective effect of this oil on the corrosion of mild steel (MS) in 1M HCl solution was tested by the measurements of Weight loss (WL), potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS). From WL measurements, the inhibiting effect was raised with the increasing of both concentration inhibitor and temperature. PDP curves led to a mixed-type inhibitor. The charge transfer process mainly controls the results of EIS measurements. The SP oil adsorption not only was discovered to obey Langmuir isotherm but showed a chemical interaction as well. The computational methods such as density functional theory (DFT), Monte Carlo (MC) and radial distribution function (RDF) simulations were also performed to analyze the possible contribution of (Z)-heptadeca-10,16-dien-7-one (ZHD) to the corrosion prevention effect of global oil.
