Background & Aim: Salvia spinosa L. is a perennial shrub and aromatic plant belongs to the family Lamiaceae. S. spinosa grows wild in some districts of Iran. The aim of this study was to identify of the chemical components of S. spinosa in Isfahan climatic conditions. Experimental: The aerial parts of the plants were collected from Isfahan province in 2014. The essen...

Background & Aim: Essential oils are isolated from different sections of plants such as flowers, seeds, leaves, stems and roots. Essential oils are applied extensively in producing of perfumes, cosmetics, foods, beverages and confectioneries and as ingredients of disinfectants and insecticides. Experimental: Essential oil are obtained by several isolation methods, such as hydrodistillation (HD...

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 studies conducted in 2007–2008 were aimed to assess how the developmental stage of common oregano affected the quality and quantity of the herb yield. The field experiment was established with the use of random blocks in four repetitions. Oregano was grown from seeding produced in a greenhouse. Herbage harvest of one-year-old plants was conducted before flowering, in budding phase, at the b...

The oil cakes of essential plants were screened for prebiotic properties further development feeds livestock animals based on these plants’ extracts. For screening, a microbiota model the chicken cecum, which was created basis an artificial intestinal medium, used. This renders it possible to simulate conditions close ones. Oligofructose, inulin, β-glucan, psyllium seeds, and apple fiber at con...

Essential oils of sixteen Chinese medicinal plants were screened for fumigant toxicity against Bemisia tabaci. The essential oil of Allium sativum exhibited the strongest fumigant activity against B. tabaci with an LC50 value of 0.11 μg/l followed by the essential oils of Agastache rugosa (LC50 = 7.08 μg/l), Illicium verum (LC50 = 8.61 μg/l), Chenopodium ambrosioides (LC50 = 8.80 μg/l), and Syz...

Whitefly (Bemisia tabaci) is an important insect pest, causing severe damage to agricultural crops. The pest was recorded in a commercial rosemary (Rosmarinus officinalis, Lamiaceae) field, colonizing rosemary variety (var.) '2', but not '11'. A series of field and controlled laboratory choice bioassays confirmed the observed phenomenon. Mature potted plants of the two varieties were randomly o...

to study the effect of planting date on morphological characteristic, yield and essential oil content of achillea millefolium sub sp millefolium.l., an experiment in a randomized complete blocks design (rcbd) with four treatments including four planting date (6 july, 1 august, 7 september and 7 october) in four replications was conducted. during the growing stage and at the end of experiment pe...
