En la investigación de la Gentianella thyrsoidea (raíz, tallo, flores) se aisló, un triterpenoide: ácido oleanólico. La estructura del triterpenoide fue elucidada por técnicas espectroscópicas (IR, NMR-'3C y DEPT).

The present research refers to Tiquila paronychoides(flor de arena). By phitochemistrey analysis has been determined the following compounds: tanins, flavonoids, alcaloids and ester [acid grass) which was isolated. The ester was characterizated by lnfrared Spectroscopy and Nuclear Magnetic Resonance Spectroscopy 1H-NMR and 13C-NMR

The yacon root is a member of the sunflower family. The roots of yacon has inuline. lnuline is a polyfructosane, which helps to moderate blood sugar levels (pass through the digestive tract unmetabolized). Yacon therefore has considerable value to dieters and people with diabetes. The quantitative analysis shows mineral macronutrients (Na, K, Mg, Ca, P). and micronutrients (Fe, Zn, Mn). The qualitative analysis shows very important secondary metabolites (amino acids, carbohydrate, reducing sugars, flavonoides)
