?-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...

The genotypic variation on physico-chemical characteristics of wild grown plums (Prunus spinosa L.) was investigated. The total phenolic contents were in a range of 117 to 407 mg GAE/100 g FW. The vitamin C was highest in yellow colored fruits (12.10 mg/100 ml). The total soluble solid content varied between 9.40% (yellow colored) and 12.90% (dark purple colored) fruits.  Antioxidant activity o...

Total phenol contents of O.vulgare were found between 54.23 mg GAE/g (U4) and 124.55 mg GAE/g (U2), respectively. While total phenol contents of O.minutiflorum change between 49.50 mg GAE/g (U5) and 126.92 mg GAE/g (S3), total flavonol contents were found between 623.87 mg RE/g (U5) and 854.53 mg RE/g (U2). Antioxidant capacity ranged from 42.31 mg AAE/g (U5) to 103.04 mg AAE/g (S3). Total ...

BACKGROUND The objective of this study was to investigate antioxidant and anti-inflammatory activity of cabbage phytochemicals. MATERIALS AND METHODS Color coordinates were evaluated by colorimetry, and the antioxidant and anti-inflammatory activities were analyzed by spectrophotometer for some common cabbage varieties. RESULTS Red heads had the highest total antioxidant contents followed b...

factors such as oxidative stress and reduced acetylcholine level have been implicated in alzheimer’s disease (ad) pathology and recently there has been a trend towards natural product research to find potential sources of antioxidants and acetylcholinesterase inhibitors in the plants kingdom. centaurea is a genus with about 500 species world wild, many of them have shown to possess biologic act...

bilberry [vaccinium myrtillus linn. (ericaceae)] fruit (vmf) has been traditionally used for treatment of bladder stones, biliary disorders, scurvy, coughs, and lung tuberculosis. vmf may have some pharmaceutical properties owing to these uses, but in vivo and in vitro studies are limited for clarification of medicinal activity and its antidiabetic and antioxidant properties are not investigate...

Total phenolic contents (TPC) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of Artemisia biennis Willd were measured in this work. The antioxidant activity was investigated by three different methods: β-carotene bleaching (BCB) test, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method and ferrous ion chelating (FIC) assay. Amo...
