This study identified flavonoid glycosides in species of the genus Alchemilla, A. procerrima, A. stricta, A. hirtipedicellata and A. sericata. A. procerrima is an endemic species for Turkey. After detailed investigation, flavonoid compounds of the species were identified for the first time. In this study, flavonoid compounds were determined by using two different chromatography techniques, TLC ...

Salvia genus, which is generally called Maryam-Goli in the Persian language, belongs to Lamiaceae family and comprises 58 species in Iran. Four flavonoids plus a steroid compound were isolated from the ethyl acetate and methanol extracts of the aerial parts of Salvia macrosiphon Boiss, using different chromatographic methods on the silica gel and sephadex LH20. The structures of the isolated co...

In a previous study, we reported that two kaempferol glycosides isolated from Laurus nobilis L., kaempferol-3-O-alpha-L-(2'',4''-di-E-p-coumaroyl)-rhamnoside (C2) and kaempferol-3-O-alpha-L-(2''-E-p-coumaroyl-4''-Z-p-coumaroyl)-rhamnoside (C3), showed strong antibacterial activities against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci. Thereafter we fo...

Six isoflavonoids having beta-galactosidase inhibiting activity were isolated from the culture filtrate of Streptomyces xanthophaeus. Their structures were determined by spectral analyses to be daidzein, daidzein 7-alpha-L-rhamnoside, daidzein 4',7-di-alpha-L-rhamnoside, genistein, genistein 7-alpha-L-rhamnoside and genistein 4',7-di-alpha-L-rhamnoside.

Willow trees have maintained their place in medicine for many years as they are herbal source of various cures. varieties considered to contain a wide range anti-inflammatory and anti-bacterial species such salicylates flavonoids. The current work is centred on the presence high bioactive pharmaceutical constituents other than salicin flavan-3-ol catechin, salicortin, complex compounds, which c...

Wound healing is a complex physiological process that is controlled by a well-orchestrated cascade of interdependent biochemical and cellular events, which has spurred the development of therapeutics that simultaneously target these active cellular constituents. We assessed the potential of Parrotia persica (Hamamelidaceae) in wound repair by analyzing the regenerative effects of its two main p...

The increasing prevalence of bacterial resistance to antibiotics is an epidemic where once easily treated infectious illnesses are becoming more difficult to treat, leading to prolonged suffering, exacerbated medical costs, and sometimes death. Methicillin-Resistant S. aureus (MRSA) is a strain of the Staph Infection causing bacteria that is resistant to penicillin-like betalactam antibiotics a...

Bioactive potential of apigenin derivative apigenin-7-O-glucoside related to its antifungal activity on Candida spp. and cytotoxic effect on colon cancer cells was studied and compared with bioactive potential of apigenin. Antifungal activity was tested on 14 different isolates of Candida spp. using membrane permeability assay, measuring inhibition of reactive oxidative species and inhibition o...

From the leaves of Cucumis sativus the following C-glycosides were isolated and identified: isovitexin 2"-O-glucoside, isovitexin, isoorientin, 4'-X-O-diglucosides of isovitexin and swertiajaponin. In the flowers of the above species chromatographically (HPLC, TLC) the presence of kaempferol 3-O-rhamnoside and 3-O-glycosides of kaempferol, quercetin, isoramnetin was revealed. The flavonoids com...

Apigenin, a widely distributed flavone, exhibits excellent antioxidant, anti-inflammatory, and antitumor properties. In addition, the methylation of apigenin is generally considered to result in better absorption and greatly increased bioavailability. Here, four putative Class II methyltransferase genes were identified from the transcriptome sequences generated from the liverwort species Plagio...
