The separation possibility of stigma from the other parts of saffron flower using its aerodynamic properties was investigated and a vertical air column was designed on the basis of the obtained results. Terminal velocities of three parts of saffron flower, including petal, stigma and anther within four days after harvest were studied. Significant difference between terminal velocity of stigma (...

Evidence Based Medicine (EBM) is now generally perceived to be the dominant operating system in conventional medicine. It is unsurprising then that some have counseled complementary and alternative medicine practitioners to resist EBM . The efficacy of medicinal herbs does need to be established and toxicity, contraindications and side effects also need to be investigated, and this is best done...

the present study was carried out to determine the potential antibacterial effect of essential oil of origanumvulgare against antibiotic resistant e.coli. in this study, the essential oil of origanumvulgare obtained by hydrodistillation was analyzed by gas chromatography coupled to mass spectrometry (gc-ms) in order to determine their chemical composition. the minimum inhibitory concentrations ...

Using a subtractive hybridization approach, differentially expressed genes involved in the light response in saffron stigmas were identified. Twenty-two differentially expressed transcript-derived fragments were cloned and sequenced. Two of them were highly induced by light and had sequence similarity to early inducible proteins (ELIP) and SOUL heme-binding proteins. Using these sequences, we s...

Considering the global popularity and also the various biological and medicinal properties of saffron, this study was conducted to assess the influence of its aqueous extracts administration on blood pressure, pressure-rate product (PRP) and electrocardiogram (ECG) indices of rat. Animals were divided to control (CTL), SAF50, SAF100, and SAF200 groups that orally received tap water, aqueous ext...

Inhibitors of acetylcholine breakdown by acetylcholinesterase (AChE) constitute the main therapeutic modality for Alzheimer's disease. In the search for natural products with inhibitory action on AChE, this study investigated the activity of saffron extract and its constituents by in vitro enzymatic and molecular docking studies. Saffron has been used in traditional medicine against Alzheimer's...

Age-related macular degeneration (AMD) is a retinal neurodegenerative disease whose development and progression are the results of a complex interaction between genetic and environmental risk factors. Both oxidative stress and chronic inflammation play a significant role in the pathogenesis of AMD. Experimental studies in rats with light-induced photoreceptors degeneration demonstrated that saf...

abstract in order to evaluate the effects of different organic and biological fertilizers on quantity and quality of essential oil of fennel an experiment was conducted in a completely randomized block design with three replications. the experimental treatments were two organic (compost and vermicompost) and two biological (pseudomonas putida and azotobacter chroococcum ) fertilizers, their all...

since the use of antibiotics in animal feeds has been banned, researches on alternative natural products that modulate ruminal fermentation have been intensified. natural compounds such as plant extracts have been considered to be replaced antibiotics as safe and sustainable alternatives. plant extracts especially essential oils and saponins have strong antimicrobial, antiparasitic, antiprotozo...

this experiment was conducted to determine the effects of dietary myrtle essential oil on small intestinal morphology and microbiology of broiler chickens. two hundred day-old broiler chickens (ross 308) were allocated to 5 treatments, 4 replications with a completely randomized design. the diets were supplemented with: no myrtle essential oil (control), each of myrtle essential oil at levels o...
