Abstract The high content of bioactive compounds in Persea americana seed has generated great interest worldwide due to its various potentialities, in which its antioxidant capacity stands out. The objective of the study was to evalúate the antioxidant activity of the aqueous and methanolic extracts of Persea americana Mili seeds, variety Hass, sold in supermarkets in the city of Maracay, Venezuela. The total phenol content of the extract was determined through the Folin-Ciocalteau method to then evalúate the antioxidant activity by three chemical methods (DPPH, FRAP and ABTS). A higher concentration of total phenolic compounds was obtained in the methanolic extract, with a statistical difference with respect to the aqueous extract. The antioxidant activity was higher in the methanolic extract in the three methods used (p <0.05). These results show the high antioxidant power of the avocado seed, considered as a waste product, which allows proposing strategies that allow its use for medicinal purposes.
