In the title compound, [Co(C(6)H(2)N(2)O(4))(C(14)H(8)N(4))(H(2)O)](n), the Co atom is bonded to one N,N'-bidentate pyrazino[2,3-f][1,10]phenanthroline (Pyphen) ligand, one N,O-bidentate pyrazine-2,3-dicarboxyl-ate (PZDC) dianion and one water mol-ecule in a distorted octa-hedral mer-CoN(3)O(3) geometry. The Co(II) atoms are bridged by the PZDC dianions, forming an infinite one-dimensional chai...

polygonatum orientale desf. (asparagaceae) is herbaceous and perennial plant grown in northern parts of iran. the rhizomes of polygonatum, known as iranian shaghagho, is used in iranian traditional medicine as tonic, aphrodisiac, wound healing, lightening, kidney stone remedy, gynecological and internal wounds healing, anti-gout and rheumatism, and anti-diabetic. the aim of this study was to ev...

In the title compound, [Ir(C(13)H(9)N(4))(C(13)H(8)NS)(2)]·3.5CDCl(3), the coordination at iridium is octa-hedral, but with narrow ligand bite angles. The bond lengths at iridium show the expected trans influence, with the Ir-N bonds trans to C being appreciably longer than those trans to N. The chelate rings are mutually perpendicular, the inter-planar angles between them all lying within 6° o...

Structural, dynamical, bonding, and electronic properties of water molecules around a soluted methane molecule are studied from first principles. The results are compatible with experiments and qualitatively support the conclusions of recent classical molecular dynamics simulations concerning the controversial issue on the presence of "immobilized" water molecules around hydrophobic groups: the...

Seaweed is a biological resource that rich in nutrients and bioactive compounds. This study aims to determine qualitatively quantitatively the compounds (flavonoids, alkaloids, steroids/terpenoids, saponins phenols) from extracts fractions of Eucheuma cottonii. The method used an experiment by conducting series experiments extracting fractionating E. cottonii data were analyzed descriptively. t...

"Ethnopharmacological" use of roots of Boerhaavia diffusa (B. diffusa) in the treatment of epilepsy in Nigerian folk medicine and reports showing the presence of a calcium channel antagonistic compound "liriodendrin" in its roots, led us to undertake the present study. The study was designed to investigate the methanolic root extract of B. diffusa and its different fractions including liriodend...

BACKGROUND Many people still experience pain and inflammation regardless of the available drugs for treatments. In addition, the available drugs have many side effects, which necessitated a quest for new drugs from several sources in which medicinal plants are the major one. This study evaluated the analgesic and anti- inflammatory activity of the solvent fractions of Moringa stenopetala in rod...

general toxicity, antiproliferative, antibacterial and antioxidant activities of caulerpa peltata j.v.lamouroux (caulerpaceae) collected from oman sea were investigated. dried, ground alga was soxhlet-extracted with hexane, dichloromethane and methanol successively. the methanol extract was subjected to vacuum liquid chromatography (vlc) fractionation on silica gel using a step gradient of diff...

This study aimed to isolate a potent antiglucosidase and antioxidant fraction from Stenochlaena palustris. Extraction was performed with hexane, chloroform, ethyl acetate, methanol, and water. Antiglucosidase, 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging and ferric reducing antioxidant power (FRAP) assays found methanol extract (ME) to be the most active. Water fraction (WF) of ME was a stro...
