002054 Saidj F;Bentahar R;Boutekedjiret C (NO, Ecole Nationale Polytechnique, 10 Avenue Hacen Badi, BP 182, EI Harrach, Alger, Algeria-162 00) : Kinetic study and optimization of the operating conditions of the extraction by steam distillation of the essential oil of Thymus numidicus (Poiret) of Algeria. J essential Oil Bearing Pl 2009, 12(2), 144-54.
In order to study the process of extraction of the essential oil of Tymus numidicus kabylica extracted by steam distillation, kinetic studies as well as an optimization of the operating conditions were achieved. The optimization was carried out by a parametric study and experiments planning method. Three operational parameters were chosen: thyme mass, steam water flow rate and porosity of the bed. The obtained results underscored a kinetic of order one with two steps. The first is faster with a recovery of more than 94% of essential oil. The optimal conditions obtained by the parametric study correspond to a : mass of 35 g, steam flow rate of 6.3 g/min. and porosity of 0.9155. The study by experiments planning realized by adopting the factorial planning of two levels of the three parameters 23, allowed on one hand, the estimation of the simple, combined interactions and triple effects of the parameters on the essential oil yield, and on the other hand, the establishment of a mathematical model describing the variations of the yield according to the studied parameters. The results reveal that the simple effect of the bed porosity is preponderant in comparison to the simple effects of the mass and the steam water flow rate. Concerning the combined effects of two parameters, the steam water flow rate and the bed porosity, is the more important. The yield is also affected by the interaction of the three parameters.

J essential Oil Bearing Pl 2009, 12(4), 381-94.
Rose-scented geranium (Pelargonium species; family. Geraniaceae; 2n = 77) is a multi-harvest, evergreen, perennial aromatic crop (Figure 1) cultivated for its essential oil. It was introduced into India from France and was initially grown as an ornamental plant on south Indian hills. Cultivation of rose-scented geranium for its essential oil was initiated in 1954 on Nilgiri hills of Tamil Nadu, from where the cultivation spread to other parts of India. Presently, the crop is cultivated on a limited scale in south Indian States of Andhra Pradesh, Karnataka, Tamil Nadu and North Indian States of Uttar Pradesh, Uttarakhand and Himachal Pradesh. The crop is commercially cultivated in a number of countries, China being the major producer and exporter of the essential oil followed by Egypt. India has always been a net importer of essential oil. The imports rose from 7.6 tonnes in the late sixties to 160-180 tonnes (natural as well as reconstituted oils). The shoot biomass on steam distillation yields the essential oil of commerce that is highly valued in the industry. More than 220 compounds have been identified and reported in the essential oil. The yield and chemical composition of the fragrant oil are influenced by number of factors.

Four different growing locations were studied to determine the influence of climatic conditions on the essential oil content and compositions of black zira (Bunium persicum). The essential oils of dried fruits were extracted by hydro distillation technique and were analyzed by capillary GC and GC-MS. According to the results the essential oil content and compositions of B. pereicum fruits significantly affected by growing locations. The largest amount of the essential oil (8.5% w/w) based on dry weight was extracted from the fruit which were harvested from Takhte-Khorjeh region and the lowest amount (3.5%w/w) based on dry weight from Jopar location was measured. Seventeen, sixteen, fourteen and fifteen components of the essential oil were identified by GC and GC-MS from Jopar, Bidoiye, Sardoiye and Takhte-Khorjeh regions respectively. The essential oils of fruits harvested from Sardoiye and Takhte-Khorje accumulated more cuminaldehyde (38.8 and 33% respectively) than essential oil of fruits harvested from Jopar and Bidoiye (15.7 and 10.9% respectively). The other major components of the essential oil of seeds of different growing locations studied in this experiment were γ-terpinen-7-al, γ-terpinene and p-cymene. The physico-chemical characteristics of the experimental soils and geographical situation and weather condition of different growing locations studied in this experiment were different, and these results confirmed the reports based on affecting of environmental factors on the quantity and quality of active substances of essential oil bearing plants.

Nepeta binaludensis Jamzad is a rare medicinal plant of Iran, which is highly endangered by severe harvesting and unsustainable herbal collection. A research was conducted to study the ecobiological background, ethnomedicinal use and chemical properties of this species in the wild habitats during the years 2003 and 2004, to understand their conservation biology as well as to predict their behavior under artificial cultivation. Results indicated that this species grows in north-facing slopes up to 50% with altitudes of 2300 to 2700 m and mean annual rainfall ranging from 350 to 370 mm and mean annual temperature of 6 to 7°C. This plant grows on light soils with a neutral pH and poor in mineral content. Height of individual plants varies from 46 to 52 cm with a crown diameter of 39 to 42 cm, a plant density of nearly 4 pl.nr-2 and a dry matter of 23 to 72 g.m-2. Plant density, biomass, plant height, crown diameter and also soil coverage of this species were decreased by increasing slopes. There was no relationship between essential oil percentage of this species and slope and altitude. The whole growth period of this species is nearly 153 days which are equivalent to 1978.9 GDD. Results showed that the aerial parts of this species are used mostly by local people to treat digestive disorders and nervous disorders and depression. Essential oils of the plant aerial parts, which were collected from two regions Dowlat Abad and Freizi, were slightly yellow and the yields were 0.5% (v/w) in both regions. Eighteen components representing 95.2% and 97.5% of the total oils of these regions were identified, respectively. The major constituent of the oxygenated monoterpene-rich oils was 1,8 Cineole (77.8% and 73.2% respectively).

Thymus vulgaris L. essential oil. J essential Oil Bearing Pl 2009, 12(3), 319-26.
Thyme herb (Thymus vulgaris L) received different treatments of organic and chemical fertilization to study the effect of these treatments on the biomass, essential oil content, and its chemical composition. Chemical fertilizers as ammonium nitrate, was used at 100 and 200Kg/ acre, while the organic fertilizer as mature compost was used at 10 and 20 mVacre, respectively. The herb was harvested two times in June and September during its' growth cycle. The obtained results indicated that the oil content of thyme at the first cut was slightly higher for chemically fertilized herb compared with the organic one. However, in the second cut there was no difference in the oil content. Organic fertilization at high level (20 m3Vacre) increased the percentage of oxygenated components in thyme oil especially thymole (51.1%) compared with any other treatments in which thymole content ranged between 31.4 - 43.2%. High levels of organic fertilization also shifted the major components of thyme oil; thymole, carvacrole, and γ- terpinene to the high margins specified by the European pharmacopoeia.

J essential Oil Bearing Pl 2009, 12(2), 155-61.
Hydrosols are aromatic waters that are produced during the distillation of aromatic plants. In this study the identity and the absolute quantity (mg/liter), of the major water-soluble aromatic components from the hydrosols of seven aromatic plants were investigated. These plants include sweet basil, peppermint, spearmint, sour orange petitgrain, lemongrass, lemon eucalyptus, and clove. Eugenol from clove hydrosol was found to be the most highly soluble component (854 mg/l hydrosol), followed by d-carvone from spearmint hydrosol (242 mg/l) and linalool from both sweet basil (171 mg/l) and petitgrain (128 mg/l) hydrosols. The investigation also revealed that, the solubility of certain aromatic component from different hydrosols is not the same, and probably depends on the chemical composition of its parent essential oil.

J essential Oil Bearing Pl 2009, 12(2), 131-6.
Lavandin (Lavandula x intermedia Emeric ex Loisel.) oil has long been used in the fragrance and perfumery industry. Lavandin is a complementary crop to Damask rose (Rosa damascena Mill.) for rose oil producers who need novel essential oil crops in Isparta region of Turkey. Although concrete, absolute and hydrosol are also produced from the lavandin flowers apart from lavandin oil, there are very limited studies on these products. The oil of var. Super grown in Isparta region was released from the glands in the flower inflorescences by steam distillation. Lavandin hydrosol (distillate water) was obtained from a by-product during the distillation. Concrete was extracted from the flower inflorescences using n - hexane, and subsequently by evaporation of the solvent in vacuum. Absolute was produced from the concrete with ethyl alcohol extraction. Essential oils from these products were analyzed on a gas chromatography-mass spectrometry (GC-MS). Two major compounds were linalyl acetate and linalool, and the concentrations of both compounds were 47.7% and 34.0% in the oil, 46.6% and 17.7% in the concrete, 45.0% and 17.2% in absolute, respectively. Lavandin hydrosol contained 55.6% linalool, but any linalyl acetate. Lavandin oil yield of the fresh inflorescences was about 1.2% (5.8% in dry flower heads). The yield of lavandin concrete was 0.9% and the lavandin concrete gave 60% of lavandin absolute.

The oil from the fruits of Ammi majus Linn. (Apiaceae) was analyzed for isoprenoids and other volatile components by GC and GC-MS. Hydrodistillation of air-dried fruits yielded 0.22% essential oil on dry weight basis. Thirty five components comprising 91% of total volatiles were identified by gas chromatographic techniques. The oil contained 13 monoterpenes (40.3%) and 15 sesquiterpenes (34.2%). The main monoterpenes were carvone (13.4%), 1,8-cineole (6.9%), α-terpinyl acetate (5.9%), trans-pinocarveol (3.2%) and citronellal (3.2%) while as the major sesquiterpenes were globulol (6.8%) and nerolidol (5.3%). The non-terpenic volatiles included high boiling hydrocarbons (7.8%) and bergapten (8.7%.

Int J pure appl Chem 2009, 4(1-2), 35-9.
A series of castor oil polyurethane poly (methyl acrylate) semi interpenetrating polymer network (SIPN CO PU PMA) were prepared from castor oil, toluene diisocyanate and methyl acrylate. The SIPN polymers obtained were characterized by thermal, chemical and mechanical properties such as tensile strength, elongation and hardness (Shore A) and compared with each other. Tensile strength and hardness (with inverse of elongation) increase in the direction of increasing isocyanate ratio and methyl acrylate content. The apparent densities were also determined and compared. The adhesive properties were applied with respect to iron to aluminum bonding. The adhesives based on IPN PU PMA were prepared and tested as adhesives for metals. The results showed that the adhesives have effective adhesion power that they can be used in a practical project.
