Composición fitoquímica del extracto de raíz de Ichthyothere terminalis de dos regiones geográficas diferentes de Colombia

The phytochemical analysis of two extracts from Ichthyothere terminalis root which were collected in the localities of Cumaral (Meta) and Abrego (Norte de Santander), Colombia is reported. Extracts were obtained with ethanol using distillation under reduced pressure and were characterized by qualitative assays and by gas chromatography coupled to a mass spectrometery (GC-MS). GC-MS analysis revealed differences in Ichthyothere terminalis compounds according to locality. Plants from Cumaral contain saponins, coumarins, and tannins, while those from Abrego contains tannins, alkaloids, coumarins and flavoniods. Plants from Abrego contain octadecadien-1-ol (53.5%), caryophyllene oxide (30.8%), hexadecanol (24.0%), trans-β-caryophyllene (13.6%), cycloisolongifolene (11.6%), germacrene D (6.0%), and 9-octadecen-1-ol (8.0%). Plants from Cumaral have citronellal (46.4%), p-cymene (6.4%), geraniol (5.0%), and citronellol (4.6%). Among the chemical compounds found, several have repellent properties, according to ethnobotanics reports from Amazonian Region. Further studies may determine the effectiveness as repellent of extracts from I. Terminalis root.
