Among health-promoting phytochemicals in whole grains, phenolic compounds have gained attention as they have strong antioxidant properties and can protect against many degenerative diseases. Aim of this study was to profile grain phenolic extracts of one modern and five old common wheat (Triticum aestivum L.) varieties and to evaluate their potential antiproliferative or cytoprotective effect i...

BACKGROUND Among the potential natural sources of bioactive compounds, those of the macroscopic fungi Phellinus spp. have been identified by previous researches. Phenolic compounds are among the major antioxidant and antimicrobial contributors due to their bioactive properties. AIMS The goal of this study was to determine the total phenolic and flavonoid contents, and its relation with the an...

Long exposure of UV radiation increases risk of skin diseases such as cancer and photoallergic reactions. UV-B (280-320 nm) radiation is mainly responsible for inducing skin problems. Skin protection is a suitable method in the fight against ultraviolet radiation induced damage. Various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they h...

Background and objectives: Salvia species are important because of their medicinal, traditional and economical uses. They are used traditionally for treatment of several diseases. The genus Salvia is represented in the Iranian flora by 61 species of which, 17 are endemic.  In the present study, the phytochemical and biological effects of two Iranian Salvia species hav...

Objectives: Leaves and flowers ofElaeagnus angustifolia contain phenolic and flavonoid compounds. These compounds have antioxidant properties that protect cells from oxidative damage. The aim of this study was to determine and analyze total phenolic and flavonoid content of leaves and flowers in two E. angustifolia variants using different solvents (ethanol and methanol). Materials and Methods:...

Preliminary phytochemical screening was carried out for pet ether, chloroform and ethanol extracts of Holarrhena antidysentrica leaves. The extracts showed the presence of various phytocompounds like alkaloids and flavonoids. In vitro antioxidant activity was carried out with all the three extracts using DPPH assay using ascorbic acid as a standard. All the extracts had shown significant antiox...

Background and Aims: This study aims to determine total phenolic, flavonoid contents in vitro biological activities of methanol (CEP-1), n-butanol (CEP-2), water (CEP-3), n-hexane (CEP-4) extracts obtained from Cephalaria procera. Methods: The phenolic content analysis, DPPH radical scavenging activities, cholinesterase, tyrosinase inhibitory properties the were evaluated using spectrophotometr...
