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...

chenopodium botrys is native to europe and asia and adventive in much of north america. the plant has been used traditionally for medicinal purposes generally, these therapeutic uses and health benefits of c. botrys are largely based on folklore rather than on scientific substantiation, making it a good candidate to gather documentations, including the phytochemical content, in vitro experiment...

objective: this study is designed to extract and examine chemical composition, antimicrobial and antioxidant activity of the hydro-distillated essential oil of murraya koenigii leaves from the south region of tamilnadu, india. matherials and methods: gas chromatography (gc) and gas chromatography-mass spectrometry (gc-ms) analysis of the essential oil result was indicates the 33 different compo...

introduction: pragmates australis (pa) (common reed) is a riverside perennial grass found in wetlands throughout temperate and tropical regions of the world. pa grows in many wetlands around rivers in iran. animal feed restriction is the main problem of iranian animal production systems and this feed resource can be fed to native livestock especially in rural areas. ensiling pa could improve it...

Patikaraparpam, a Siddha formulation in prepared by trituration of potash alum with egg albumin followed by calcinatin. The three authentic laboratories made parpams as well as six commercial samples have been examined for their chemical composition. The analytical data that emerged from the analysis of the above samples showed that seven parpams contained only aluminium sulphate and they did r...

We review our current knowledge of the solar chemical composition as determined from photospheric absorption lines. In particular we describe the recent significant revisions of the solar abundances as a result of the application of a time-dependent, 3D hydrodynamical model of the solar atmosphere instead of 1D hydrostatic models. This has decreased the metal content in the solar convection zon...

background & aim:mentha longifolia (l.) huds is an aromatic perennial herb that belongs to the   family lamiaceae. the aim of this study was to identify chemical composition of aerial parts   (including leaf, stem and flowers) of m. longifolia collected from   (kamu mountain) isfahan province. experimental: the essential oils were extracted   using the hydrodistillation method and analysed by g...

ten chromite ores from ophiolite complexes in se iran were analyzed mineralogically by xrd, chemically by xrf, and mineral chemistry by epma. the identified paragenesis of silicate minerals of chromite ores with the x-ray diffraction is pronounced differently. it consists of secondary phases formed as serpentine, cr-containing chlorite (kaemmererite), chromic garnet (uarovite) with preserved pa...
