Antimicrobial and phytochemical activity of methanolic extract and its fractions of Jatropha curcas Linn. (Eurphorbiaceae) stem bark

The stem bark of Jatropha curcas Linn (Euphorbiaceae) widely used in ethno medicine was studied. The methanolic extract (ME) and methanolic extract fractions (MEF) namely: chloroform fraction (CF), ethyl acetate fraction (EAF) and methanol fraction (MF) of J. curcas were subjected to antimicrobial evaluation and phytochemical screening. Results showed that saponins and steroids were present...

Synthesis and antibacterial activity of metal complexes of barbituric acid

Cobalt (II), copper (II), iron (III), manganese (II) and nickel (II) complexes of barbituric acid were synthesized and characterized by infrared and ultraviolet spectroscopy. The ligand and the complexes have been screened for in vitro antibacterial activity against a range of Gram-positive and Gram-negative bacteria (Bacillus authracis, Bacillus cereus, Bacillus stearothemophilus, Bacilis subtilis,...

Simultaneous assay of codeine phosphate and diphenhydramine hydrochloride in cough mixtures by zero-order derivative UV spectrophotometry

This study evaluated a zero-order derivative UV spectrophotometric method for the simultaneous determination of binary components, codeine phosphate and diphenyhydramine HCl in cough mixtures. The method was based on the measurement of zero-order derivative amplitudes at isosbestic points, 258 and 264 nm, for the assay of codeine phosphate and diphenylhydramine HCl (0.05 to 0.15 mg/ml). The method does not...

Study on the properties of copolymer hydrogel obtained from acrylamide/2-hydroxyethyl methacrylate by the application of gamma radiation

Synthesis of copolymer hydrogels from aqueous solution of acrylamide/2-hydroxyethyl methacrylate (HEMA) has been performed with radiation processing technology using Co-60 gamma source. The influence of radiation dose and concentration of HEMA on gel content, swelling properties and thermal stability of copolymer hydrogel has been investigated. Gel content of prepared hydrogel obtained maximum at the radiation dose of...
