Development of Compositions and Technologies for Producing Tablets with Hydroxythyrozol-standardized Extract of Olive Leaves
Introduction. The article presents the results of a study of the physicochemical properties of dry extract of olive leaves, standardized by hydroxythyrozol - a biologically active substance that is part of the chemical composition of aerial parts of the olive tree.Aim. The purpose of the study is to develop tablet Formulations containing dry extract of olive leaves and to standardize by hydroxythyrozol by reversed-phase-HPLC method on the main substancecontent.Materials and methods. Substance of dry extract of olive leaves, microcrystalline cellulose (Avicel® PH-112), Aerosil® (Aeroperl® 300 Pharma), Ludipress® (Ludipress®), lactose, potato starch, sodium salt of carboxymethyl starch, magnesium stearate, direct pressing, HPLC.Results and discussion. Studies of the physicochemical properties of dry extract of olive leaves have been carried out. Selected excipients for the study of tablettable masses. Formulations for further tabletting have been developed. A complex of studies of the obtained tablets was carried out according to Russian Pharmacopoeia XIV for compliance with quality indicators.Conclusion. The biological properties of dry extract of olive leaves are have been studied, indicating the prospect of developing drugs based on it. Formulations of tablets with dry extract of olive leaves have been developed and their quality indicators have been investigated.
