detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Preparation, composition analysis and antioxidant activities of konjac oligo-glucomannan.
Konjac oligo-glucomannan (KOG) was prepared by degradation of konjac glucomannan (KG) using β-mannanase. The hydrolysis process was monitored by the viscosity of the enzymatic hydrolysates. Factors affecting the enzymatic hydrolysis of KG were investigated, and the optimum hydrolysis conditions were as follows: time 2h; temperature 50°C; pH 6.0; and enzymatic concentration 150 U/g. Under these ...
متن کاملAntioxidant activities of enzymatic extracts from brown seaweeds.
Potential antioxidative activities of enzymatic extracts from seven species of brown seaweeds were evaluated using four different reactive oxygen species (ROS) scavenging assays containing DPPH (1,1-diphenyl-2-pricrylhydrazyl) free radical, superoxide anion, hydroxyl radical and hydrogen peroxide scavenging assay. The brown seaweeds were enzymatically hydrolyzed to prepare water-soluble extract...
متن کاملChanges in Total Phenol and Some Enzymatic and Non-Enzymatic Antioxidant Activities of Rose-scented Geranium (Pelargonium graveolens) in Response to Exogenous Ascorbic Acid and Iron Nutrition
Strong antioxidant activity of Pelargonium graveolens is well known. The question addressed in this study was whether different concentrations of exogenous ascorbic acid (AsA) and iron (Fe) were able to influence antioxidant activity and total phenol content (TPC) of geranium. Thus, three levels of Fe (0, 20 and 40 µM) and three levels of AsA (0, 1 and 2 mM) in nutrient solution were c...
