The stereochemical course of the cyclisation reaction catalysed by the bacterial 1,8-cineol synthase from Streptomyces clavuligerus was investigated using stereospecifically deuterated substrates. In contrast to the well investigated plant enzyme from Salvia officinalis, the reaction proceeds via (S)-linalyl diphosphate and the (S)-terpinyl cation, while the final cyclisation reaction is in bot...

The objectives of this work were to optimize hydro-distillation extraction Salvia officinalis L. essential oil (SoEO) and evaluate the in vitro scavenging capacity free radicals DPPH·, NO·, ABTS+, ability reduce Fe3+. optimization SoEO by was carried out using response-surface methodology Box–Behnken. cytotoxicity anti-proliferative capacities evaluated measuring cell viability then modeled. Tw...

AIM The aims of this study were to evaluate the effects of intramammary infusion of sage (Salvia officinalis) essential oil (EO) on milk somatic cell count (SCC), milk composition parameters and selected hematology and serum biochemical parameters in 20 Awassi ewes affected with subclinical mastitis. MATERIALS AND METHODS The dried leaves of sage were used to extract the EO by hydrodistillati...

The antifungal activity and the chemical composition of essential oils (EOs) from some Mediterranean autochthonous plants were investigated against Malassezia pachydermatis, a fastidious opportunistic yeast usually involved in canine external otitis. Minimum inhibitory concentrations (MICs) of Anthemis nobilis, Citrus limon, Citrus paradisi, Illicium verum, Lavandula hybrida, Mentha piperita, O...

background: the aim of this study was to examine the renoprotective effect of hydro alcoholic sage (salvia officinalis: so) leaves extract against gentamicin-induced nephrotoxicity in rats. methods: in this experimental study forty male sprague dawley rats weighing 200-300 g were randomly divided into 5 groups; (1) the rats without treatment (control), (2) intraperitoneally injected with normal...

Extensive research suggests that a number of plant-derived chemicals and traditional Oriental herbal remedies possess cognition-enhancing properties. Widely used current treatments for dementia include extracts of Ginkgo biloba and several alkaloidal, and therefore toxic, plant-derived cholinergic agents. Several non-toxic, European herbal species have pan-cultural traditions as treatments for ...
