Abstract

Ten extracts of wild Algerian plants were, prepared daily just before handling by suspending a weighed amount of dry plant material in boiling tap water at room temperature. The artificial urine was prepared immediately before use by mixing in a T-type mixing chamber. Mixture agitation was maintained to prevent sedimentation; Percentage of inhibition of crystallisation (1%) was calculated as previously described. Extracts of plants used in this study was found to potently inhibit the nucleation, growth and aggregation phases of calcium oxalate crystallization.
