herbal medicines can be used as the potential sources of anti-oxidative compounds to help the treatment of diseases associated to oxidative stress. in this paper, the ferric reducing antioxidant power (frap) activity of four lamiaceae herbal extracts, which traditionally applied in oxidative stress related diseases, has been evaluated and total phenolics contents of these extracts determined by...

This study investigated the antioxidative and obsteoblast differentiation promoting activity of the phenolics isolated from the 70% ethanol extract of the roots of Livistona chinensis. Two new phenolics, (2R,3R)-3,5,6,7,3',4'-hexahydroxyflavane (1), and phenanthrene-2,4,9-triol (2), together with six known phenolics 3-8, were isolated and identified on the basis of extensive spectroscopic analy...

Pigmented potato cultivars were ranked by a consumer panel for overall acceptance, and acceptance of aroma, appearance, and flavor. Potatoes were analyzed for total phenolics, anthocyanins and carotenoids. Concentrations of total phenolics in yellow and purple potato cultivars were 2-fold greater (P < 0.001) than in the white cultivar. Anthocyanins were low to non-detectable in white and yellow...

To evaluate the ripening-dependent changes in phytonutrients, seven commercial cultivars (two general and five cherry) of tomatoes were cultivated under greenhouse conditions. Fruits were harvested at breaker, turning, pink, light red, and red stages of each cultivar, and antioxidant contents, color attributes, and antioxidant activities were measured. During ripening process, lycopene content ...

Six species of lesser known edible fruits from Western Ghats of India were analysed for their anthocyanin, ascorbic acid, total phenolics and flavonoid levels and their antioxidant activities using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The data obtained shown the anthocyanin, ascorbic acid, total phenolics and flavonoid levels were significantly higher in the methanol extract of Maho...

Epidemiological studies suggest that consumption of fruit rich in phenolic compounds is associated with health-protective effects due to their antioxidant properties. For these reasons quality evaluation has become an important issue in fruit industry and in breeding programs. Phytochemical traits such as total phenolics, flavonoids, anthocyanins, L-ascorbic acid, sugar content and relative ant...

Background and objectives: People interest in traditional medicine has increased recently; however, traditional herbal medicines should be transformed into modern forms of medicine to increase patient acceptance. In this investigation, a polyherbal traditional combination “Monzej-e-balgham” has been based on according to Iranian traditional medicine (ITM) manuscripts and its qu...

BACKGROUND Free radicals are implicated in several metabolic diseases and the antioxidant therapy has gained an utmost importance in the treatment. The medicinal properties of plants have been investigated and explored for their potent antioxidant activities to counteract metabolic disorders. In this study, the chemical composition and free radical scavenging potential of leaf gall extracts (et...

Among 60 vining species growing almost exclusively in the Northern hemisphere, only the grapevine (Vitis vinifera L.) (Vitaceae) is the single species largely used in the global wine industry. Grapes are important sources of antioxidants, such as phenolic compounds. The antioxidant activity of these polyphenols is considered much higher than that of the essential vitamins, thus contributing sig...
