This study exploited the application of pulsed electric field (PEF) on recovery polyphenols from aerial parts Sideritis scardica, tepals Crocus sativus, and fruits Vitis vinifera. Short pulses 10 μs in a period 1 ms were applied to plant material, while different intensities, 1.2 2.0 kV/cm tested optimize procedure. The content total polyphenolic profile extracts evaluated. Along with PEF sampl...

Three growth inhibitors which might be involved in phototropism of Sakurajima radish (Raphanus sativus var. hortensis f. gigantissimus Makino) hypocotyls, were isolated as crystalline forms from light-exposed radish seedlings and identified as cis- and trans-raphanusanins and 6-methoxy-2,3,4,5-tetrahydro-1,3-oxazepin-2-one (designated raphanusamide). The cis- and trans-raphanusanins inhibited g...

abstract there is a world-wide effort to reduce the amount of chemicals used in crop production by introducing modern biological and ecological methods. one possible alternative is allelopathy. a laboratory trial was carried out to investigate of alleopathic potential of angelica . in this study the effect of different concentrations of aqueous extract of angelica herb was investigated on seed ...

objective(s): quinolinic acid (qa)-mediated excitotoxicity has been widely used as a model for studying neurodegenerative disorders. recent studies suggested that saffron (crocus sativus) or its active metabolite, i.e. safranal, exerts pharmacological actions on central nervous system including anxiolytic, anticonvulsant, and neuroprotective properties. the present study aimed to investigate th...

objective(s) anti-helicobacter pylori effects of saffron (crocus sativus l., iridacea) and its major constituents, crocin and safranal, were evaluated. materials and methods macerated aqueous and methanol extracts tested against 45 clinical isolates of helicobacter pylori, using paper disc diffusion method (ddm) on modified egg yolk emulsion agar (eye agar). four antibiotics also tested against...

objective: inflammation is one of the major components of asthma. our aim was to evaluate the effects of c. sativus extract on total and differential white blood cells (wbc) count in lung lavage fluid (llf) of ovalbumin-sensitized rats. materials and methods: forty rats were divided into five groups (n = 8 for each group) as control (c), sensitized with injection and inhalation of ovalbumin (oa...
