The purpose of this research study was to isolate and describe the structural characteristics of the alkaloids present in the roots of the plant Tabernaemontana markgrafiana J.K. Macbr (known as Uchu sanango) using spectroscopic and spectrometric methods. To carry out the process, the root of Tabernaemontana markgrafiana J.K. Macbr. (2,100 kg) was dried at a temperature of 20 °C for 15 days. Subsequently, an ethanolic extraction was performed by maceration with ethanol for 30 days, changing the solvent every 48 hours. The ethanol was removed by reduced pressure in a rotary evaporator until a dry extract with a weight of 138,20 g was obtained. From the ethanolic extract (138,20 g), different fractions were obtained: an acidic alkaloidal extract (3,34 g), an acidic alkaloidal residue (58,26 g), a basic alkaloidal extract (593,3 mg), and a basic alkaloidal residue (6,23 g). In conclusion, ...
