The ultrasound-assisted extraction of phenolic compounds from Epimedium brevicornu Maxim was modeled using response surface methodology. A Central Composite Design (CCD) was employed to optimize three extraction variables, including ethanol concentration (X 1), extraction time (X 2), and ratio of aqueous ethanol to raw material (X 3), for the achievement of high extraction yield of the phenolic...

Objectives: Potato (Solanum tuberosum L.), as a whole food, contains high levels of vitamins and important antioxidants including phenolic acids, carotenoids and flavonoids. The objective of this study was to determine the total phenolic content and antioxidant activities of three common potatoes (Solanum tuberosum) cultivars in Iran i.e., Savalan, Agria and Sante. Materials and Methods: Pheno...

background: thymus daenensis celak. is one of the medicinal plants which cultivated in iran. this plant involve high amount of polyphenols including thymol and carvacrol, which were reported to possess the high antioxidant activity. objective: antioxidative activity (aoa) and chemical constituents of thymus daenensis essential oil (tdeo) were examined. also, the effect of thermal treatments (80...

some plant extracts have been reported to exhibit antimicrobial properties. plant based pesticides appear to be an alternative for the synthetic pesticides because of their less dangerous impacts. the objective of this study was to assess the inhibitory activity of brassica napus water extract on mycelial growth of six phytopathogenic fungi rhizoctonia solani, phythophtora drechseleri, pythium ...

In this study investigated the effect of putrescine sprayed (0.5 & 1mM) on Chamomile (Matricaria chamomilla L.) and the changed of Anthocyanin, Phenolic compounds, POX & CAT Antioxidative enzymes were examined. The results show that Putrescine treatments increased hydrogen peroxide in seedlings to compare control. Phenolic compound content under putrescine treatments are different. Phenolic com...

Pegagan (Centella asiatica (L.) Urban) is a herbal plant that contain secondary metabolite compounds like phenol and flavonoid. NaCl salinity one of abiotic stress enhanced synthesis some metabolites in plants. This study was investigated the effect to phenolic compound, total flavonoid antioxidant activity pegagan leaves. were treated with five different concentrations, 0 mM (1), 50 (2), 100 (...

pharmacological activities of 6-(4-hydroxy-3-methoxyphenyl)-hexanonic acid (hmpha), a phenolic compound, isolated from the extract of pycnocycla spinosa was investigated on ileum motility in vivo and in vitro . ileum motility was examined by measuring charcoal movement through the gut in mice. in addition, antidiarrhoeal activity of hmpha was assessed and compared with standard drug; loperamide...

The aim of this work was to compare the antioxidant activity of the extract of flaxseed and its alkaline hydrolysate in two model systems: lipid autoxidation of triacylglycerols of sunflower oil (TGSO)-in a homogeneous lipid media and during β-carotene-linoleate emulsion system. In addition, pure lignans were tested. The material was defatted with hexane and then phenolic compounds were extract...
