INDIRECT SPECTROPHOTOMETRIC DETERMINATION OF NEOMYCIN BASED ON THE REACTION WITH CERIUM (IV) SULFATE

A simple and sensitive spectrophotometric method has been described for the assay of neomycin either in pure form or in pharmaceutical formulations. The proposed method was based on the oxidation of the studied drug by a...

CHEMICAL CONSTITUENTS FROM DENDROPHTHOE FALCATE

The ethyl acetate extract of the roots and leaves of Dendrophthoe falcate yielded apigenin-8-C-β-D (2"-O-β-D-glucopyranosyl)-glucopyranoside. The isolated compounds were characterized by U V, I R, N M R and mass spectral...

SYNTHESIS, CHARACTERIZATION AND DNA INTERACTION STUDIES OF COPPER(II) COMPLEX OF 4(3H)-QUINAZOLINONE-DERIVED SCHIFF BASE

A novel copper(II) complex of quinolin-4(3H)-one derived Schiff base ligand was synthesized and characterized by elemental analyses, IR, 1H-NMR, MS, UV–Vis, magnetic moments, conductance measurements and thermal studies....

CO2 EFFECT ON THE FLAME VELOCITY IN GASEOUS FLAMMABLE MIXTURES. PRELIMINARY TESTS ON STOICHIOMETRIC ETHYLENE-AIR MIXTURE

Paper presents several tests regarding the effect of CO2 on the flame propagation in stoichiometric ethylene-air mixture, at atmospheric and subatmospheric initial pressures. Results are discussed and compared with liter...
