background: white button mushroom (agaricus bisporus) is one of the most sensitive agricultural crops after harvesting and its antioxidant properties tend to decrease during post-harvest storage with the passage of time. objectives: the possible role of exogenous application of malic acid as dipping treatment on bioactive components and antioxidant properties of sliced white button mushroom dur...

antioxidant properties of ghrelin have been demonstrated in recent studies. in the present study, theeffects of chronic administration of ghrelin on the motility and plasma membrane integrity of rat spermatozoa during incubation at 37ºc were investigated. thirty 45-day-old male wistar rats were divided into control and treatment groups. rats in the treatment group were daily injected subcutaneo...

effects of yeast extract (ye) (0, 0.05, 0.1, 0.2, 0.5 and 1%) were investigated on rosmarinic acid (ra) accumulation and tyrosine aminotransferase (tat) gene expression in melissa officinalis seedlings at different time intervals (4 and 17 hours). based on the results, only ye concentrations of 0.05%, 0.1%, and 0.2%, for the 17-hour treatment, significantly stimulated ra biosynthesis pathway. a...

Phytochemical investigations of Calotropis procera leaves have led to the isolation of two new compounds: quercetagetin-6-methyl ether 3-O-beta-D-4C1-galacturonopyranoside (3) and (E)-3-(4-methoxyphenyl-2-O-beta-D-4C1 -glucopyranoside)-methyl propenoate (4), along with eleven known metabolites: nine flavonol and two cinnamic acid derivatives. All metabolites were isolated for the first time fro...

Cyperus rotundus Linn. (Family: Cyperaceae), commonly known as Motha is a turf grass which grows everywhere including lawns . It has wide range of medicinal and pharmacological applications. It is used in traditional system of medicine and exhibits anti-inflammatory, anti-arthritic, antipyretic, analgesic, antidiabetic, antidiarrhoeal, cytoprotective, antmutagenic, antimicrobial, antioxidant, c...

In recent years, a considerable number of structurally unique metabolites with biological and pharmacological activities have been isolated from the marine-derived fungi, such as polyketides, alkaloids, peptides, lactones, terpenoids and steroids. Some of these compounds have anticancer, antibacterial, antifungal, antiviral, anti-inflammatory, antioxidant, antibiotic and cytotoxic properties. T...

Chromatographic separation of an aqueous MeOH extract of Wisteria sinensis leaves has yielded six known flavonoids, two triterpene aglycones and the new acylated flavone glycoside chrysoeriol-7-O-[2''-O-(5'''-O-caffeoyl)-β-Dapiofuranosyl]-β-D-glucopyranoside (1). All metabolites were isolated for the first time from the genus Wisteria. Their structures were established on the basis of their chr...
