[The photocolorimetric determination of reducing agents using sodium metavanadate as reagent]. / Consideratii privind determinarea fotocolorimetrica a unor reducatori utilizind ca reactiv metavanadatul de sodiu.

The oxidative properties of Vv can be used in the photocolorimetric determination of those reducers which give no other reactions with vanadium ions-penta and tetravalent. Two determination scales of the reducers were elaborated and the isoniazide hydrazide from tablets was dosed with satisfactory results.

[An analytical study of 2 dimethylxanthine derivatives with action at the level of the cardiovascular system]. / Studiul analitic a doi derivati ai dimetilxantinei cu actiune la nivelul aparatului cardiovascular.

The analytical investigation of two derivatives of dimenthylxantine series, conventionally termed Imfilin and Carprofilin, is presented. For the quantitative determination of these derivatives the authors suggest spectrophotometric methods in UV which gave good results in the physicochemical control of the substances and of certain pharmaceutical forms (injectable solutions, tablets). The suggested methods were applied in observing the stability of these pharmaceutical forms as well as in their determination in the biological material.
