ABSTRACT Several species of the genus Passiflora are distributed all over South America, and many of these species are used in popular medicine, mainly as sedatives and tranquilizers. This study analyzes the chemical profile of extracts of four Passiflora species used in folk medicine, focusing on the flavonoids, alkaloids and saponins. We employed simple and fast fingerprint analysis methods by high performance liquid chromatography, ultra performance liquid chromatography and capillary electrophoresis techniques. The analysis led to the detection and identification of C-glycosylflavonoids in all the plant extracts, these being the main constituents in P. tripartita var. mollissima and P. bogotensis. Saponins were observed only in P. alata and P. quadrangularis, while harmane alkaloids were not detected in any of the analyzed extracts in concentrations higher than 0.0187 ppm, the detection limit determined for the UPLC method.
