1. There is no effective anti-H5N1 avian influenza agent. 2. A chemical compound— BFDBSC—can inhibit H5N1 virus infection in cell cultures, and such inhibition might be attributable to its halogenated benzoyl residues. 3. This pilot study assessed anti- H5N1 activity and toxicity of four chemical compounds with halogenated benzoyl residues in cell culture system. 4. Two compounds—FPBFDBSC and B...

The essence oil from the fresh rhizomes of Kaempferia rotunda L. was isolated by water distillation and analyzed by gas chromatography-mass spectrometry (GC/MS) method. Fifty seven components were identified in the rhizomes oil, which accounted to 99.74% of the oil. The major components were endo-borneol (9.30%), dehydro iso androsterone acetate (9.12%), naphthalene, decahydro-1,1,4a-trimethyl-...

Tansy, Tanacetum macrophyllum (Waldst. & Kit.) Sch. Bip., is often misidentified by herb collectors as yarrow, Achillea grandifolia Friv. With the former, cases of poisoning induced by its ingestion are well documented, but the latter is widely used for ethnopharmacological purposes. The aim of this study was to estimate, based on the volatile metabolite profiles of the two species, the potenti...

We have tested acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities of nineteen essential oils obtained from cultivated plants, namely one from Anethum graveolens L. (organic fertilizer), two from Foeniculum vulgare Mill. collected at fully-mature and flowering stages (organic fertilizer), two from Melissa officinalis L. (cultivated using organic and chemical ferti...

BACKGROUND Hypercholesterolemia is a major risk factor for development of atherosclerosis. The present study was conducted to evaluate the potential effect of ginger oil alone or combined with rosemary oil as hypocholesterolemic agent in rats fed high fat diet. MATERIALS AND METHODS Healthy female albino rats (n=80) weighting about (150-180 g) were included in this study divided into two equa...

Glucuronic acid has been found in the urine of a variety of experimental animals (1, 2), chiefly in the form of conjugation products with phenolic substances and steroids (2, 3). The presence of glucuronides is widely interpreted as evidence of the ability of the animal organism to make use of the conjugation reaction to eliminate a great variety of toxic substances. Variations in the aglucone ...

In this present study, it was aimed to determine the composition of essential oil obtained by water distillation from aerial parts Origanum acutidens. The analysed GC-FID and GC/MS. Carvacrol (69.3%), p-cymene (8.3%), y-terpinene (6.3%), β-caryophyllene (2.7%) borneol (2.2%) were found as main constituents. addition, headspace-solid phase microextraction using a Polydimethylsiloxane-Divinylbenz...

It was previously reported by the authors (1) that, in a normal rat with daily administration of 100 mg/kg borneol and intraperitoneal injection of 400 mg/kg glucuro nolactone for the period of 13 days, the amounts of total glucuronic acid, of o-glucuronide and of 1-ascorbic acid excreted in rat's urine, increased significantly, and that, in a bilate rally adrenalectomized rat administrated dai...

AIM The purpose of this study was to evaluate how increasing NaCl salinity in the medium can affects the essential oils (EOs) composition and phenolic diterpene content and yield in leaves of Salvia officinalis L. The protective role of such compounds against NaCl stress was also argued with regard to some physiological characteristics of the plant (water and ionic relations as well as the leaf...

the genus tanacetum l. is one of the most important medicinal plant that contains 28 species in iran, 12 of them are endemics. this paper reports the essential oil composition of tanacetum hololeucum (bornm.) podlech; tanacetum kotschyi (boiss.) grierson, growing wild in iran. plant flowers were collected from different zones of dizin in north of iran. all samples were hydro-distilled (clevenge...
