UNLABELLED Crataegus succulenta Schrad. ex Link is widely spread in North America. A literature survey revealed no studies on the chemical composition and biological effects of this species. AIM The aim of the present study was to investigate the phenolic content, free radical scavenging and 15-lipoxygenase inhibitory effects of Crataegus succulenta leaf and flower extracts. MATERIAL AND ME...

Proanthocyanidins (PAs) are products of the flavonoid pathway, which also leads to the production of anthocyanins and flavonols. Many flavonoids have antioxidant properties and may have beneficial effects for human health. PAs are found in the seeds and fruits of many plants. In apple fruit (Malus × domestica Borkh.), the flavonoid biosynthetic pathway is most active in the skin, with the flava...

phenolic compounds including flavonoids and phenolic acids are plants secondary metabolites. due to their ability to act as antioxidant agents, there is a growing interest to use those components in traditional medicine for cancer prevention or treatment. the aim of this study was to measure the amounts of total phenolics and flavonoids as well as anti-proliferative effect of aqueous extract of...

stachys genus with medicinal properties and high polymorphic features has been considered oneof the largest genera of lamiaceae. the aim of this study was to determine the flavonoid patternvariations and flavonoid groups in ten stachys species belonging to two sections; fragilicaulis,and aucheriana. the studied species were collected from natural habitats in iran and analysedfor their flavonoid...

Temporal changes in total flavonoid content (TFC), composition, free radical scavenging activity and metabolism-related gene expression of three Prunus humilis cultivars with distinctively different fruit colors were investigated this study. The highest TFCs all observed at the initial sampling stage (young-fruit stage, YFS), which then declined gradually until ripening. dark-red-fruited cultiv...

Background: Carissa bispinosa, Ficus sycomorus, and Grewia bicolar are edible fruit plants that grow in the wild. The plants produce yellow-, red-, and purple-colored fruits and thus can be good sources of flavonoids for fighting oxidative reactions in humans, food, and the pharmaceutical industry. The present study aimed at isolating flavonoids from C. bispinosa, F. sycomorus, and G. bicolar f...

bark extract of pinus pinaster contains numerous phenolic compounds such as catechins, taxifolin, and phenolic acids. these compounds have received considerable attentions because of their anti-inflammatory, antimutagenic, anticarcinogenic, antimetastatic and high antioxidant activities. although p. pinaster bark has been intensely investigated in the past; there is comparably less information ...

BACKGROUND The present study was carried out to assess the phytochemical and anti-dermatophytic effect of the leaf and bark extracts of Xylosma longifolium Clos. The leaf and stem bark are used by the indigenous people of Manipur, India for treatment of skin diseases. METHODS The leaves and stem barks of Xylosma longifolium were extracted using petroleum ether, chloroform and methanol respect...

Compounds that promoted the growth of pollen tubes were isolated from the style of Rhedodendeon muerenatum and were identified as azalein, (+)-catechin, and (-)epicatechin. Among these compounds, 50-100ppm of (+)-catechin or (-)-epicatechin increased the growth of pollen tubes in thmetlia japoniea, R. mueronatum, Slyrax japoniea, and Pinus densij7bra by 16-20%. These compounds had no significan...

plants are almost reach sources of phenolic compounds such as flavonoids which are the most importantnatural antioxidants. antioxidant compounds are essential for protecting human body against oxidativestress. however use elicitors could increase the antioxidant activity of plant. the purpose of this studywas to evaluate the effects of chitosan on the content of phenolic and flavonoid compounds...
