    Peach palm (Bactris gasipaes) is a fruit of great nutritional importance due to its content of bioactive compounds, including carotenoids, fatty acids, and phenolic compounds, which are associated with antioxidant and anti-inflammatory properties. Currently, there is growing interest in the search for natural sources of functional compounds and in the development of sustainable extraction technologies that enable the utilization of plant resources with potential applications in the food and pharmaceutical industries. The aim of this study was to obtain extracts derived from peach palm flour using Soxhlet and subcritical propane–butane extraction methods, compare their chemical profiles, and evaluate their antioxidant and anti-inflammatory capacities. Extraction yield was determined gravimetrically, the extracts were characterized by thin-layer chromatography (TLC), antioxidant activity was assessed using the DPPH assay, and anti-inflammatory activity was evaluated through the inhibition of albumin denaturation. The results showed that the Soxhlet method achieved a higher extraction yield than the subcritical propane–butane method, as well as differences in the chemical profiles of the extracts obtained. On the other hand, subcritical propane–butane extraction exhibited the highest antioxidant capacity, reaching DPPH radical inhibition values of up to 77.20%, whereas extracts obtained by Soxhlet extraction showed the greatest anti-inflammatory activity, with protein denaturation inhibition values of up to 96.00%. It was concluded that peach palm flour represents a promising source of bioactive compounds and that both extraction methods constitute viable alternatives for obtaining value-added functional ingredients.
