Antioxidants and allelopathy are activities that valorize plants, attracting the interest of his study. The aim of this study was to evaluate the antioxidant activity (AAO), allelopathic (ALL) and bioactive substances present in leaves eight plant species from the Tamshiyacu-Tahuayo Community (Loreto¬-Peru). AAO assessment was performed by the method of capture free radical DPPH, using dried leaves and crushed, soaked in methanol for fifteen days, preparing solutions 0.01- 5.0 mg / ml and 0.1 mMol DPPH, the reading is performed in the spectrometer equipment UV / vis at 517 nm., for ALL was performed by the method of Petri dishes methanolic extracts from fresh leaves pregerminated Latuca sativa used with concentrations of 0.1- 50.0 mg / ml against the growth of seeds sativa, reading is performed by measuring the hypocotyl and radicle of the seedling. The results of species with high AAO are Virola calophylla, Caryocar glabrum and Tapirira guianensis, the percentage of which have a greater than 50% at concentrations of 5.0 mg / ml inhibition. Also, high ALL species are Xylopia benthami, Lacmellea standleyi and Virola pavonis, reaching EC50 for radicle at lower concentrations to 1.0 - 50.0 mg / ml. The concentration of phenolic compounds for these various species of 11521.7 to 32181.7 mg / 100g, 103.1 to 144.3 flavonoid mg / 100g and from 0.063 to 0.177 proanthocyanidins mg / 100g. The total alkaloids varied from 0.0 to 68.2 mg / 100 g. Each plant species has been recovered through its antioxidant and allelopathic assessment, showing differences between them.
