objective: antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions. materials and methods: in this research the antioxidant potential of the fresh fruits of 4 cultivars (a to d) of malus domestica (m. domestica) cultivated in the kashan, qamsar area was evaluated. the antioxidant activity of the samples were evaluated using two complementary antioxidant...

in this study, the effectiveness of chitosan coating treatment to control weight loss and maintaining fruit quality of apricot was investigated. fruits were coated with 0.25%, 0.5% and 0.75% chitosan as well as distilled water (control). following treatments, fruits were stored at 0?c and 80 ? 2% relative humidity for 25 days. the weight loss, total soluble solids (tss), titratable acidity (ta)...

?-amylase inhibitory activities of ethanol extracts from six selected iranian salvia species (s. hydrangea dc., s. hypoleuca benth., s. officinalis l., s. reuterana boiss., s. verticillata l. and s. virgata jacq.) were examined, using in vitro model. in addition, antioxidant capacities (dpph• radical scavenging) and total flavonoid cotents of the extracts were also determined. the results showe...

background and objective: garlic, in different types, is a very common food ingredient all over the world. traditionally, garlic is fermented in grape vinegar to produce garlic pickles; in this study, to produce a novel fermented food, garlic was fermented in kombucha beverage; then, antibacterial and chemical properties and color changes of garlics fermented in kombucha and vinegar were compar...

Total polyphenol content, catechins content, and antioxidant capacities of green, dark, oolong, and black teas made from Camellia sinensis in China were evaluated. The total polyphenol content of 20 samples of tea was in the range of 7.82-32.36%. Total catechins content was in the range of 4.34-24.27%. The antioxidant capacity of tea extract was determined by the oxygen radical absorbance capac...

strawberry (fragaria ananassa duch.) is a good source of natural antioxidants. fruits from eight strawberry (fragaria ananassa duch.) cultivars (‘kurdistan’, ‘merck’, ‘camarosa’, ‘paros’, ‘queen elisa’, ‘ventana’, ‘selva’ and ‘pajaro’) were harvested at ripen stage and analyzed for total phenolic content, total anthocyanin content, vitamin c, total soluble solid and total antioxidant activity. ...

Aqueous extracts of 30 plants were investigated for their antioxidant properties using DPPH and ABTS radical scavenging capacity assay, oxygen radical absorbance capacity (ORAC) assay, superoxide dismutase (SOD) assay, and ferric reducing antioxidant potential (FRAP) assay. Total phenolic content was also determined by the Folin-Ciocalteu method. Antioxidant properties and total phenolic conten...

Soluble and bound phenolic compounds were extracted from different varieties of millet types namely, finger millet, foxtail, and proso millet cultivated at dry and intermediate climatic zones in Sri Lanka. The extracts were examined for their total phenolic content (TPC), total flavonoid content (TFC), and proanthocyanidin content (PC). The antioxidant activities were meassured by reducing powe...

objective: there has been a growing interest in finding plants with biological active ingredients for medicinal application. materials and methods: three colors of petals of althaea officinalis (a. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. results: the reddish pink flowers of a. officinalis have more antioxidant...

xanthine oxidase plays crucial roles in the production of reactive oxygen species (ros), and uric acid in blood which may lead to gout, one of the oldest known forms of arthritis amongst humans. summer savory (satureja hortensis l.) a medicinal/spice exhibits antioxidant activity, but unknown effects on xanthine oxidase activity. here, for the first time, we examined the effects of s. hortensis...
