Modeling of the dissolution kinetics of arbutus wild berries-based tablets as evaluated by electric conductivity

Lyophilized powder (LP) from Algerian arbutus wild berries (Arbutus unedo L.) was obtained. This present paper reports about the dissolution (releasing) properties of LP-based tablets, evaluated through the electric conductivity (EC) of distilled water which is employed as surrounding medium, at thr...
