Satureja wiedemanniana (Lallem.) Velen (Lamiaceae) is an endemic species of Turkey. Aerial parts of the plant collected from eleven different localities in Turkey were subjected to hydrodistillation to yield essential oils which were analysed by a GC/MS system. Carvacrol, thymol, p-cymene and gamma-terpinene were found as the main constituents. Antibacterial evaluation of the oils was also carr...

abstract indian meal moth, plodia interpunctella hübner (pyralidae) is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repel...

Effect of plant essential oils on seed germination and seedling growth of Parthenium hysterophorus was examined. Essential oils of Eucalyptus, Camphor, and Lemongrass were used in the experiments at different concentrations (0 to 20 ml.l). Water imbibed (36 h) seeds were germinated at 25°C ± 1 in petriplates containing 3 layers of filter papers soaked in distilled water and added with 1.5 ml of...

Plant oils with their long linear methylene sequences are attractive substrates for polymeric materials, such as long-chain aliphatic polyesters and polyamides. Existing biotechnological routes for their conversion to long-chain linear a,ro-dicarboxylic acid derivatives have recently been complemented by chemical catalytic conversions. This contribution discusses and compares the conversion of ...

The essential oils of the aerial parts of Ocimum basilicum Linn.var. pilosum (Willd.) Benth., an endemic medicinal plant growing in China, was obtained by hydrodistillation and analysed by GC-MS. Fifteen compounds, representing 74.19% of the total oil were identified. The main components were as follows: linalool (29.68%), (Z)-cinnamic acid methyl ester (21.49%), cyclohexene (4.41%), alpha- cad...
