Plantas medicinais: estudo da eficiência de solventes na extracção de componentes das folhas da bridelia cathartica bertol F

Abstract

This Licentiate work report follows on from others carried out in the country, within the scope of research on medicinal plants, so widely used by practitioners of traditional medicine. In addition to the scientific value that it may eventually represent in the determination of active principles, this study essentially aims to verify the laboratory conditions existing in the Department of Chemistry of the Faculty of Sciences of the University Eduardo Mondlane for research in the area of ​​Chemistry of Natural Products, particularly plants medicinal. Thus, two chromatographic methods, namely Thin Layer Chromatography (TLC) and Medium Pressure Column Chromatography (MPLC) were used to obtain results on the efficiency of solvents in extracting components from the plant under study. From the study it is concluded that there are conditions for conducting studies in this area, as illustrated by the results obtained, namely in the extraction, in solvent economy, through the application of the MPLC technique and the effectiveness of the TLC analysis in the determination of the polarity gradient and to monitor the MPLC.
