Abstract

This thesis describes the application of the thin-layer chromatography (TLC) method for assessing the identity of aescin and L-arginine substances. The study was carried out under laboratory conditions in accordance with the requirements of the State Pharmacopoeia of the Republic of Uzbekistan and the EuropeanPharmacopoeia. Separate mobile phases were selectedfor aescin and L-arginine, and the Rf values of reference and test samples were compared. The obtained results demonstrated that the identity of the tested substances corresponded to the reference standards. The TLC method was confirmed to be a rapid,reliable,andeffectiveapproachforpharmaceuticalqualitycontrol.
