An improved HPLC method for determination of colocynthin in colocynth
Background and objectives: Colocynthin is the major active secondary metabolite of colocynth, Citrullus colocynthis (L.) Schrad, which has been used in traditional and ethno medicine of many countries. It could be considered as an active marker for quality control of colocynth and its herbal products. Analysis and standardization of colocynth and its herbal preparations are a critical...
متن کاملUDP-N-Acetylgalactosamine: globoside a-3-N-Acetylgalactos- aminyltransferase
A UDP-N-acetylgalactosamine:globoside a-3-N-acetylgalactosaminyltransferase has been purified over 3500-fold in 4% yield from a Triton X-100 extract of canine spleen microsomes by affinity chromatography on globoside acid-agarose. Sodium dodecyl sulfate gel electrophoresis of the purified enzyme revealed two major bands with molecular weights of 66,000 and 56,000. Judging from the molecular wei...

متن کاملAn Improved Method for the Determination
A routine discrete sample method for the determination of soil 'available' phosphorus, using manual or automated colour complex preparation, is described. After extraction, orthophosphate is determined colorimetrically using a stable 12molybdoantimonylphosphate complex. This improved method gives results comparable to those obtained using the existing Dickman and Bray procedure. When used with ...
متن کاملThe UDP N-acetylgalactosamine 4-epimerase gene is essential for mesophilic Aeromonas hydrophila serotype O34 virulence.
Mesophilic Aeromonas hydrophila strains of serotype O34 typically express smooth lipopolysaccharide (LPS) on their surface. A single mutation in the gene that codes for UDP N-acetylgalactosamine 4-epimerase (gne) confers the O(-) phenotype (LPS without O-antigen molecules) on a strain in serotypes O18 and O34, but not in serotypes O1 and O2. The gne gene is present in all the mesophilic Aeromon...
