This paper aimed to make the phytochemical study and determine the concentration of total flavonoids from the leaves of Piper peltatum and Piper aduncum from the Amazon region. The species were collected from Rio Santiago district, Condorcanqui Province, Amazonas Region. The phytochemical screening was performed using staining and precipitation reagents. Total flavonoids were quantified by Kostennikova method. It was found a high diversity of metabolites in both species such as alkaloids, triterpenes and steroids, flavonoids, phenols and tannins, reducing sugars, quinones, fatty compounds, coumarins and resins, and the presence of saponins only in species of Piper aduncum L. The content of total flavonoids in species of Piper peltatum L. and L. Piper aduncum was 1.8 ± 0.16 and 2.51 ± 0.15 g equivalents to quercetin per 100g of dry leaves respectively. P. aduncum showed the highest concentration of flavonoids expressed as quercetin with statistically significant difference. (p <0.05).
