Anti-psoriatic activity of Givotia rottleriformis in rats.

Objectives: To evaluate the antipsoriatic activity of Givotia rottleriformis bark in rats.

Materials And Methods: The antipsoriatic activity of the ethanol extract was investigated using ultraviolet B (UV-B)-induced photodermatitis model in rats. The animals were divided into four groups (6/groups).

Estimation of pioglitazone hydrochloride and metformin hydrochloride in tablets by derivative spectrophotometry and liquid chromatographic methods.

Two simple and accurate methods of analysis to determine pioglitazone hydrochloride (PIO) and mefformin hydrochloride (MET) in combined dosage forms were developed using second-derivative spectrophotometry and reversed-phase liquid chromatography (LC). PIO and MET in combined preparations (tablets) were quantified using the second-derivative responses at 227.55 nm for PIO and 257.
