BACKGROUND The drive toward the use of medicinal plants has been increasing in recent years. They have few side effects and a large variety of efficient components. OBJECTIVES This study was designed to investigate the analgesic effects of hydroalcoholic Rhus coriaria leaf extract (HRCLE) in a rat model. MATERIALS AND METHODS A total of 42 adult male rats were divided into seven groups: a c...

background & aim: identification, characterization and detection of medicinal plants chemical composition are very important for phytochemical scientific source. sumac is one of the medicinal plants in the world that uses for industrial and pharmacological application. in this study, chemical composition of rhus coriaria has been investigated. experimental: chemical composition of the matu...

Reduction-oxidation of native Rhus vernicifem laccase produces specific long-lived spectral changes in the near UV and visible region. These can be attained 1) in aerobic reduction experiments, 2) from partially and fully reduced laccase molecules reacting with 0 2 , 3) by reacting peroxylaccase with 2 reduction eq, and 4) upon reoxidation of fully reduced laccase by 2 mol eq of HzOz. The spect...

Rhus tripartitum (Ucria) Grande leaves and fruits were investigated for their contents in phenolic compounds, essential oils, fatty acids. Chemical composition antioxidant potential of these secondary metabolites using chromatographic tools different tests. Results displayed high amounts compounds leaves, concomitant with important potentialities, probably due to richness acids flavonoids as id...

Introduction: There is an increasing concern regarding the emergence of highly antibiotic resistant bacteria and therefore interests for the development of new antibiotics are increasing worldwide. Plant extracts are popular for having the least side effects and being natural .We have investigated antibacterial activity of extracts from four Lorestan medicinal plants including Artemisia Persi...

The enzyme, ß-glucogallin: 1,2,3,6-tetra-O-galloyl-ß-D-glucose 4-O-galloyltransferase, which catalyzes the last common step in the biosynthesis of the two subclasses of hydrolyz­ able tannins, i.e. gallotannins and ellagitannins, was purified 868-fold from leaves of peduncu­ late oak ( Quercus robur, syn. Q. pedunculata) to apparent homogeneity. Polyclonal antibod­ ies against this pivotal enzy...

Alcoholic extracts of N. jatamansi and R. succedanea, the two common Ayurvedic antiasthmatic drugs, were found to inhibit histamine and serotonin induced reduction in tidal air recorded as overflow of air insufflated through the lungs in spinal dogs. Inhibitory effects of the drugs against the bronchoconstrictors was also indicated fi om the reduction in perfusion pressure through isolated guin...
