A spectrophotometric method is proposed for the determination of the polyphenols content in aqueous extracts of plants. The method is based on the reduction of Cu(II) to Cu(I) by polyphenols, in the presence of bicinchoninic acid in a buffered medium (ammonium acetate, pH 7.0) with the formation of Cu(I)/BCA complexes. A calibration curve of absorbance (at 558 nm) vs tannic acid concentration i...
The article presents new records for five alien species previously unknown from the flora of United Arab Emirates (UAE): Euphorbia cyathophora Murr. (Euphorbiaceae), Samolus valerandi L. (Myrsinaceae), Oldenlandia umbellata (Rubiaceae), Cardiospermum halicacabum (Sapindaceae), and Corchorus aestuans (Malvaceae s. l. / Tiliaceae). All them have been recorded first time emirate Fujairah in easter...
The in vitro ability of Pothomorphe umbellata ethanolic crude extract to inhibit matrix metalloproteinase (MMP) in normal cornea and in cornea after alkali injury was demonstrated. Corneas of albino rabbits were injured with 1 N NaOH for 20 s. After 48 h the corneas were excised, homogenized and analyzed for MMP-9 (92 kDa), pro-MMP-2 (72 kDa) and MMP-2 (67 kDa) activity by gelatin zymography. T...
The cytotoxicity of the dichloromethane crude extract (DCE), obtained from the aerial parts of Pothomorphe umbellata (L.) Miq (Piperaceae), was evaluated against nine human cancer cell lines (MCF-7, NCI-ADR/RES, OVCAR-3, PC-3, HT-29, NCI-H460, 786-O, UACC-62, K-562). The DCE presented antiproliferative activity with good potency against all cell lines at low concentrations (between 4.0 and 9.5 ...
The present work examines the protective mechanisms of methanol extract of Oldenlandia umbellata (MEOU) in carbon tetrachloride intoxicated rats. Rats were treated with carbon tetrachloride at the dose of 1 ml/kg body weight intraperitonially once in every 72 hrs for 16 days. The hepatoprotective activity of methanol extract of Oldenlandia umbellata was evaluated by measuring levels of serum ma...
