background and objectives: astragalus is one of the most abundant genera of flowering plants in iran. there are a few reports on phytochemical investigation of this valuable genus. saponins, flavonoids and polysaccharides have been reported as the most important metabolites in astragalus species. in the present research, we aimed to identify the foremost constituents of astragalus maximus. meth...

The purpose of this study was to simultaneously develop anti-hyperuricemic and anti-wrinkle source using Camellia japonica leaf (CJ). CJ extract prepared. Its contents biomarkers biological activities were then analyzed. First, we investigated the extraction efficiency. rate 10% or less with hot water 80% ethanol. HPLC analysis revealed that contained rutin, hyperoside, isoquercitrin, chlorogen...

From the aerial parts of Phlomis spinidens, two new flavonol bisglycosides, phlomisflavosides A (1) and B (2), were isolated together with the known compounds, astragalin, isoquercitrin, lamiridoside, phlomoside A, shanzhiside methyl ester, 8-O-acetylshanzhiside methyl ester, phlorigidoside C, rodioloside (=salidroside), forsythoside B, citroside A and lariciresinol-4'-O-beta-D-glucoside. The s...

INTRODUCTION Microbiologically derived cyclodextrin glucanotransferase (CGTase) is used commercially as a processing agent in manufacture of food, pharmaceuticals, and cosmetics. Its toxic potential was evaluated in anticipation of use in the production of alpha-glycosyl isoquercitrin, a water-soluble form of quercetin. METHODS Following OECD guidelines, CGTase, produced by Bacillus pseudalca...

Okra seeds (OSD) have been proved to possess significantly anti-fatigue activity and due to their high contents of flavonoids and polyphenols. While, the quality of OSD is easily affected by harvest time, region and other factors. In this research, the rapid method based on Fourier transform near infrared (FT-NIR) spectroscopy was developed for quality assessment of okra seeds. Firstly, 120 sam...

The plant species Arbutus unedo shows numerous beneficial pharmacological effects (antiseptic, antidiabetic, antidiarrheal, astringent, depurative, antioxidant, antihypertensive, antithrombotic, and anti-inflammatory). For the medicinal use, standardization of extracts is a necessity, as different compounds are responsible for different biological activities. In this paper, we analyze monthly c...
