background: essential oils, as secondary plant compounds, present a safer alternative to conventional insecticides in insect control programs. so five essential oils including eucalyptus, mint, yarrow, oregano and rosemary oils were evaluated against the brown-banded cockroach supella longipalpa . methods : evaluation was done against the 3 rd and 4 th instar nymphs using three bioassay methods...
conclusions based on these observations, wide variation is detected in the chemical composition of the oil obtained from the same plant in different seasons. materials and methods the oil was extracted by hydro-distillation from two samples collected in different seasons, and analyzed by gc-fid and gc-ms. results in total, 18 and 20 components were identified and quantified in the oil of summer...
the chemical composition of the essential oil obtained from the aerial parts of laurus nobilis l. has been examined by gas chromatography (gc) and gc- mass spectrometery (ms). the main components of the oil were identified. 1,8-cineole was the major component in the oil together with b-terpinyl acetate, terpinene-4-ol, a-pinene, b-pinene, p-cymene, linalool and terpinene-4-ylacetate. the essent...
We study the influence of the emulsification process on encapsulation efficiency of drugs in double water-in-oil-in-water emulsions. Two drugs were used, first vitamin B12 which can be considered as a model drug and secondly a suspension of Cydia pomonella Granulovirus (CpGV), a virus used in organic agriculture to protect fruits against the Carpocapse insect. Encapsulation is measured by class...
Background and Objectives: Despite unique characteristics of tahini, adequate biotechnical studies have not been carried out on tahini. In recent decades, functional food production such as probiotics has increased because of positive effects on the consumer health. Studies have verified that probiotics do not include appropriate survivability in fat ambiences. Hence, the present study was carr...
cuminum cyminum linn. (umbelliferae) is a plant, which has been used as a toothache remedy in folk medicine of iran. in this study, the potential anti-nociceptive and anti-inflammatory activities of the fruit essential oil of c. cyminum has been evaluated in chemical (formalin test) and thermal (tail-flick test) models of nociception and formalin model of acute inflammation in rats and mice. th...
Liquid-encapsulated lysozyme microspheres were successfully synthesized using a sonochemical method. The encapsulation of four different liquids, namely, sunflower oil, tetradecane, dodecane and perfluorohexane on the formation, stability and morphology of the lysozyme microspheres was studied. Among the four different liquids used for encapsulation, perfluorohexane-filled microspheres were fou...
This paper reports the preparation of encapsulated particles as models of cells using an alternating droplet generation encapsulation method in which the number of particles in a droplet is controlled by a microchannel to achieve one-to-one encapsulation. Using a microchannel in which wettability is treated locally, the fluorescent particles used as models of cells were successfully encapsulate...
Oil entrapped floating alginate beads of curcumin were developed and characterized. Cremophor EL, Cremophor RH and Tween 80 were utilized to improve the solubility of the drug. The oil-loaded floating gel beads prepared by emulsion gelation method contained sodium alginate, mineral oil and surfactant. The drug content and % encapsulation declined as the ratio of surfactant was increased. The re...
