Simple, sensitive and accurate spectrophotometric method was proposed for the micro determination of vanadium (V) using salicylaldehyde acetoacetic acid hydrazone (SAAH) as a reagent. The method was based on the formatio...
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...
A series of novel substituted 10H-Phenothiazines were synthesized via Smiles rearrangement using specific precursors. Synthesized Phenothiazines in form of heterocyclic base were then treated with appropriate sugar to yi...
A simple and rapid HPLC enatioseparation of D,L-phenylalanine (Phe) and D,L tryptophan (DL-Trp) was developed. The resolution of enantiomers couples was based in the formation of mixed chelating complexes between copper...
An EPR study of the paramagnetic centers formed by gamma irradiation of polycrystalline Na2TeO4 •2H2O (BDH) was made. In the EPR spectra recorded at room temperature, the presence of two types of radicals was observed; t...

SPECTROPHOTOMETRIC DETERMINATION OF TRACE AMOUNTS OF VANADIUM (V) USING SALICYLALDEHYDE ACETOACETIC ACID HYDRAZONE. APPLICATIONS
Simple, sensitive and accurate spectrophotometric method was proposed for the micro determination of vanadium (V) using salicylaldehyde acetoacetic acid hydrazone (SAAH) as a reagent. The method was based on the formatio...
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 AND EVALUATION OF ANTIOXIDATIVE PROPERTIES OF SUBSTITUTED 10H-PHENOTHIAZINES WITH THEIR RIBOFURANOSIDES
A series of novel substituted 10H-Phenothiazines were synthesized via Smiles rearrangement using specific precursors. Synthesized Phenothiazines in form of heterocyclic base were then treated with appropriate sugar to yi...
HIGH PERFORMANCE LIQUID CHROMATOGRAPHY CHIRAL SEPARATION OF D,L-PHENYLALANINE AND D,L-TRYPTOPHAN WITH QUATERNARY MOBILE PHASE MIXTURE BY COPPER MIXED CHELATE COMPLEXATION
A simple and rapid HPLC enatioseparation of D,L-phenylalanine (Phe) and D,L tryptophan (DL-Trp) was developed. The resolution of enantiomers couples was based in the formation of mixed chelating complexes between copper...
KINETICS OF THE THERMAL DISAPPEARANCE OF RADICALS FORMED DURING THE RADIOLYSIS OF SODIUM TELLURATE (Na2TeO4 •2H2O)
An EPR study of the paramagnetic centers formed by gamma irradiation of polycrystalline Na2TeO4 •2H2O (BDH) was made. In the EPR spectra recorded at room temperature, the presence of two types of radicals was observed; t...
