QUANTITATIVE DETERMINATION OF ANTIOXIDANT POTENTIAL OF ARTEMISIA PERSICA

An experimental protocol was designed to investigate the total flavonoids, phenolics and antioxidant potential of methanol extract of Artemisia persica. For initial screening of antioxidant activity DPPH on TLC was emplo...

LIQUID CHROMATOGRAPHY – QUO VADIS?

ELECTRIC FIELD EFFECT ON OPTICAL DICHROISM OF SOME AZODYES DISSOLVED IN COMPENSATED CHOLESTERIC LIQUID CRYSTAL

In the paper are presented the results obtained in the study of the optical dichroism of some azodyes dissolved in a compensated mixture of cholesteryl chloride and cholesteryl-nonanoate under the electric field action....

FTIR AND MOLECULAR MODELING STUDY OF THE INTERACTION BETWEEN b-CYCLODEXTRIN AND POLYCHLOROBIPHENYLS

The production of polychlorobiphenyls (PCB’s) is forbidden but they are found frequently in different environmental compartment due to their high stability. In this paper the interaction between β-cyclodextrin (β-CD), a...

DEVELOPMENT OF A NEW ETHANOL BIOSENSOR WITH ELECTROPOLYMERISED MELDOLA BLUE AS MEDIATOR

An amperometric biosensor for ethanol was developed based on immobilization of alcohol dehydrogenase on screen-printed electrodes modified with electropolymerised Meldola Blue carried out by cyclic voltammetry in the ran...
