A kinetic study for calcium oxalate crystallization in the presence of Viburnum opulus extract

Abstract

In this study, the effects of Viburnum opulus (VP) extract on crystal kinetics and morphology of calcium oxalate were investigated in vitro in an attempt to elucidate the mechanisms of formation of calcium oxalate calculi and further help in seeking inhibitors for preventing the crystallization. The results showed that Viburnum opulus extract affected the crystal growth of calcium oxalate. It was found that VP tested in this study was effective on crystallization rate and behaved as an inhibitor for calcium oxalate crystallization. The presence of VP inhibited the crystal growth of calcium oxalate possibly throug adsorption onto the active growth sites for crystal growth.
