Background: Some fungi have double host attacks for animals and plants, among them Alternaria alternata. Using a local medicinal plant such as Ephedra alanda is one way to fight its spreading. Aim: Evaluate the effect of different extracts against mold Material Methods: This work used solvent by successive extraction (Hexane, Chloroform, Ethyl acetate, Methanol) total alkaloids evaluate Anti- a...

A method utilizing bovine serum albumin (BSA) as buffer additive for chiral separation by means of capillary electrophoresis is described. Parameters that affect chiral separation, such as buffer pH, buffer concentration, BSA concentration, and organic modifier, are investigated. Baseline resolution of ephedrine-pseudoephedrine and norephedrine-norpseudoephedrine isomers are achieved in an unco...

Analysis of common volatile constituents between herbal pair (HP) Ephedra sinica Stapf (ESS)-Zingiber officinal Rosc (ZOR)and its single herb was performed by the method of GC-MS and alternative moving window factor analysis (AMWFA). Identification of the compounds was also assisted by comparison of temperature-programmed retention indices (PTRIs) on the OV-1 column with authentic samples. AMWF...

Ma huang, the dried plant stem of ephedra intermedia Schrenk et C.A., contains an ephedrine-type alkaloid and has been used for weight loss. Neuropeptide Y (NPY), a 36-amino acid peptide, is concentrated in the hypothalamus and stimulates feeding desire. In this study, the effect of ma huang on the expressions of NPY in the hypothalamus of rats was investigated using immunohistochemistry. Food-...
