Se determinó la presencia de hecogenina en frutos verdes de las tres procedencias. Esta estructura molecular corresponde a una sapogenina esteroidal no reportada en esta especie. ABSTRACT This research includes the study of aerial parts (fruits) of lulo de monte (Solanum quitoense var. Septentrionale). The main objective of this research was to determine the secondary metabolites and especially the presence and quantity of alkaloidal saponins, which are common in the Solanaceae family. These

The study was conducted with species of three different origins and three different maturing stages gathered in the department of Cundinamarca, Colombia between 2.400 and 2.600 meters above sea level during the period from March to June. Sapogenins were extracted, isolated and purified through various techniques used for this purpose. The presence of saponins was proved through physical and chemical analysis, and the structural elucidation through nmr and ir spectroscopic techniques. The presence of hecogenin in green fruits from the three sources was determined. This molecular structure corresponds to a non-steroidal sapogenin reported in this species.
