BACKGROUND 6-Gingerol is one of the most pharmacologically active and abundant components in ginger, which has a wide array of biochemical and pharmacologic activities. In recent years, the application of microwave-assisted extraction (MAE) for obtaining bioactive compounds from plant materials has shown tremendous research interest and potential. In this study, an efficient microwave-assisted ...

Pomegranate seed oil was extracted in a closed-vessel high-pressure microwave system. The characteristics of the obtained oil, such as fatty acid composition, free fatty acidity, total phenolic content, antioxidant activity and colour, were compared to those of the oil obtained by cold solvent extraction. Response surface methodology was applied to optimise extraction conditions: power (176-300...

It is reported that salvianolic acid B, a bioactive phenolic compound contained in the root of Salvia miltiorrhiza, exhibits a much stronger activity in free radical scavenging and antioxidance than those of vitamin E. When a conventional refluxing method is adopted to extract salvianolic acid B from the root, in which the materials are subjected to higher temperature and longer time, the yield...

Edge information is useful for various remote sensing applications : classification, relief reconstruction, image analysis. A lot of methods have been proposed to process edge extraction, with respect to the hypothesis of additive noise. All these methods are usually based on differential operators followed by a non local-maxima suppression or a zero-crossing search. In SAR imagery, presence of...

ferula galbaniflua boiss is one of the natural plants of iran that its exudates, barijeh gum, can be used in food industry. the present study explored the properties of a new gum extracted from tubers of ferula galbaniflua. for this purpose, barijeh gum was extracted from crude exudates by alcoholic extraction with 90% ethanol. the purity of gum was relatively high, and it composed mostly of sa...

Restrictions on the use of synthetic antioxidant such as butylated  hydroxyanisole  (BHA) and butylated  hydroxytoluene (BHT) are being imposed  because of  their carcinogecity. In this investigation  optimization  of phenolic extraction  process  frome  methanolic (80%)  extract (v/v) of  elaegnus  angustifolia  through  Response  Surface Methodology  by fulin cio- calteu is  performrd  for op...

Nowadays the researches have indicated the fact that using synthetic antioxidants as food additives in edible oils can have adverse effects on human health. So preparing antioxidation resources for reduction of oxidation stress effects is important. The aim of this project was, representing a natural antioxidant source with frap test. The present study optimized the ultrasound assisted extracti...

OBJECTIVE Unexpected post-extraction bleeding is often experienced in clinical practice. Therefore, determining the risk of post-extraction bleeding in patients receiving anticoagulant therapy prior to surgery is beneficial. This study aimed to verify whether the HAS-BLED score was useful in predicting post-extraction bleeding in patients taking warfarin. DESIGN Retrospective cohort study. ...
