The essential oil (EO) of Cota tinctoria var. was analyzed using GC-FID / MS. A total 51 compounds were determined from this taxon, accounting for 99.79% in hydrodistillation. Monoterpenes the primary chemical class volatile organic EO (36.1%, 13 compounds). Borneol (18.1%), camphor (14.9%), and β-pinene (11.3%) major components C. tinctoria. antimicrobial activities n-hexane, acetonitrile, met...

extracts obtained from the petals of rosa damascena (rosaceae) are used in iranian folk medicine as remedies for the treatment of some inflammatory diseases. in this study the hydroalcoholic extract and essential oil of the plant were investigated for its possible anti-inflammatory and analgesic activities. the extract was administered at the doses (p.o.) of 250, 500 and 1000?mg/kg and the dose...

Hydrodistilled volatile oils, as well as the extracts from waste water after hydrodistillation from the aerial parts of Satureja montana and Satureja cuneifolia, growing wild at Mt. Biokovo (Croatia), were analyzed by GC-MS. Sixty compounds were identified in four samples. The major constituents of essential oil obtained from the plant material of S. montana were carvacrol (63.4%) and thymol (1...

Background and objectives: Dorema ammoniacum D. Don (Apiaceae) is a monocarpic plant endemic to central Iran. The gum resin of this species is a known therapeutic agent in Iranian, Indian and Western traditional medicines. The aim of the present study was to investigate essential oil constituents and evaluation of antioxidant and antibacterial activities of the essential oils and extracts of D....

The essential oil extracts of western juniper oil (Juniperus occidentalis) and Port-Orford-cedar oil (Chamaecyparis lawsoniana) were evaluated for possible dermal toxic effects on mice and rabbits. Mice were tested for their response to both extracts utilizing a local lymph node assay. Western juniper oil extract at 0.5% and 5% concentrations did not show a stimulation index (SI) greater than n...

Background: Natural antioxidants with plant origin are incorporated to foods in the forms of essential oils or extracts. They can retard lipid oxidation and control spoilage bacteria in foodstuffs (e.g. meat products). Objective: This work was aimed to evaluate the effect of nitrite partial replacement with Mentha piperita essential oil (MPEO) on oxidative, microbial and sensory properties of...

The objective of this research was to study the biological activities of various extracts and the chemical composition of the essential oil Trigonella monantha C. A. Mey. subsp. monantha by gas chromatography (GC) and gas chromatography-mass spectroscopy (GC-MS), from the compounds derived from the aerial parts. The overall results of T. monantha tests allow us to conclude various extracts [hex...

Nepeta cataria L. has been used in traditional medicine of some countries. Here the cytotoxic and apoptogenic activity of methanol extracts, n-hexane, dichloromethane, ethyl acetate, n-butanol, and acqueous extracts and the essential oil obtained from the aerial parts of the plant were evaluated with PC3, DU-145 and MCF-7 cell lines. Cell viability, histograms of PI stained fragmented DNA in ap...
