Introduction: plant species of the genus Cecropia are widely distributed in South America, including several areas in Colombia, where they are popularly known as "yarumos". These plants have been reported to have hypoglycemic, analgesic, antiulcer, wound-healing and antimalarial properties. There are few reports on phytochemical studies of Cecropia metensis Cuatrec. and Cecropia membranacea Trécul. Objective: contribute to the phytochemical study of the ethanolic extract obtained from leaves of Cecropia metensis (syn. Cecropia peltata var. candida Velasquez) and Cecropia membranacea. Methods: a preliminary phytochemical study was conducted of ethanolic extract from petiolate leaves of Cecropia metensis and Cecropia membranacea collected during the rainy season in the Department of Meta in Colombia, using conventional tube assays and thin-layer chromatography. Profiles were also developed using thin-layer chromatography and high performance liquid chromatography (HPLC). Results: ethanolic extracts from petiolate leaves of Cecropia metensis and Cecropia membranacea collected during the rainy season were characterized by the presence of flavonoids, tannins, steroids and terpenes, and the absence of alkaloids, saponins, anthracene derivatives, coumarins and terpene lactones. HPLC profiles revealed the great complexity of the extract, with compounds of high, medium and low polarity, as well as appreciable absorptivity at 210 and 220 nm. Conclusions: ethanolic extracts from leaves of Cecropia metensis and Cecropia membranacea collected in the rainy season contained a moderate variety of secondary metabolites: terpenes, steroids, flavonoids and tannins. Reported for various species of the genus Cecropia, these compounds could be of interest for pharmacological purposes. Chromatographic profiles also revealed that the two species studied are very similar in their phytochemical composition.
