“…The large distribution of L. stoechas in many countries bordering the Mediterranean Sea is fairly unique within the genus Lavandula. The reported medicinal properties of this species are also very diverse, since L. stoechas has traditionally been used as expectorant, carminative, stimulant, wound healing adjuvant [4] [5], antispasmodic, sedative, diuretic, therapy for rheumatic diseases [6], analgesic, and antiseptic [7]. Most of these properties are due to the essential oil (EO) fraction of the plant.…”

In an effort to develop local productions of aromatic and medicinal plants, a comprehensive assessment of the composition and biological activities of the essential oils (EOs) extracted from the aerial flowering parts of wild growing Lavandula stoechas L. collected from eleven different locations in northern Algeria was performed. The oils were characterized by GC-FID and GC/MS analyses, and 121 compounds were identified, accounting for 69.88-91.2% of the total oil compositions. The eleven oils greatly differed in their compositions, since only 66 compounds were common to all oils. Major EO components were fenchone (2; 11.27-37.48%), camphor (3, 1.94-21.8%), 1,8-cineole (1; 0.16-8.71%), and viridiflorol (10; 2.89-7.38%). The assessed in vitro biological properties demonstrated that the DPPH-based radical-scavenging activities and the inhibition of the β-carotene/linoleic acid-based lipid oxidation differed by an eight-fold factor between the most and the least active oils and were linked to different sets of molecules in the different EOs. The eleven EOs exhibited good antimicrobial activities against most of the 16 tested strains of bacteria, filamentous fungi, and yeasts, with minimum inhibitory concentrations (MICs) ranging from 0.16 to 11.90 mg/ml.

“…Identification of CIN was performed by matching with GC-MS results of National Institute of Standards and Technology (NIST, Gaithersburg, Maryland, USA) mass spectral library data. The amount of CIN in leaves was determined using internal standard calibration method in GC-MS and toluene was used as internal standard (Giray et al, 2008). 1,8-Cineole was found as a major active component of leaves by GC-MS analysis.…”

“…It is multi-component chemicals that will produce a product that is highly aromatic and more concentrated than the original plant [2]. Essential oils has a wide range of uses and promises various significant benefits to human and industry such as in aromatic and fragrances [5][6][7], medical activities [3,8,9], as insect repellents and pesticides [10][11][12], cosmetics [11,13], as a natural additive for food flavouring [4,14], and pharmaceutical industries [1-3, 5, 11].…”

Abstract. Steam temperature of extraction plays a major role in steam distillation essential oil extraction. The process variable gives large effect to the output yield and quality of the oils. This study proposed a robust hybrid fuzzy combined with PID (HFPID) controller to control the steam temperature in the extraction process. The controller was attached to a hydro-diffusion to overcome the current issue facing by conventional steam distillation. The hydro-diffusion steam distillation plant enhances oil recovery by minimizing oil waste in boiling water. HFPID controller is expected to improve system performance at transient and steady state in order to promises the best quality of essential oil. The temperature control was achieved by controlling the voltage fed to the heater ranging from 0V to 5V via digital-toanalogue converter (DAC). The HFPID controller using 49 rules was compared with the conventional PID controller in term of rise time, settling time, percentage overshoot (%OS) and RMSE. From the result, the real time performance of HFPID controller reveals that this controller is compatible for the system because able to minimize the output error at transient state and gave the faster response with small overshoot, settling time and RMSE.
