Chemical and biological study of saponins isolated from three malagasy species belonging to Caryophyllaceae, Pittosporaceae and Solanaceae families

2013

This thesis was carried out in the Laboratory of Pharmacognosy, in the Pharmacy section of the University of Burgundy. The principal theme of this laboratory is the research of natural compounds from tropical biodiversity, mainly saponins. In this context, the study of Malagasy plants, Polycarpaea corymbosa Lamk. (CARYOPHYLLACEAE), Pittosporum verticillatum Bojer subsp. verticillatum (PITTOSPORACEAE), Solanum incanum L. and S. heteracanthum Dunal. (SOLANACEAE) led to the isolation of fifteen natural glycosides by column chromatography, medium pressure liquid chromatography, flash chromatography, and vacuum liquid chromatography. The structures were elucidated mainly by the use of spectrosco…
