Abstract The leaves and fruit of Brosimum alicastrum, a neotropical tree, contain many phenolic compounds, although it is still unclear which extraction techniques and protocols are most efficient. We analyzed the effect of solvent-to-tissue ratio (STR) and lyophilized tissue type (LT) in ultrasound-assisted extraction (UAE) of B. alicastrum leaf and seed elements on total phenolic compounds content (TPC) and extraction yield (EY). Phenolic compounds from lyophilized fruit peel, seed skin, seed and leaf were extracted with ethanol-distilled water (1:1, v/v) in an ultrasonic bath at three STRs (20, 40 and 60 mL g−1) for 30 min, at 30 °C and 100% amplitude. The two factors (LT and STR) and their interaction affected UAE results. The highest STR value (60 mL g−1) produced the highest TPC, while seed tissue had the highest TPC and fruit peel tissue the highest EY. Ultrasound-assisted extraction effectively extracts phenolic compounds from B. alicastrum using the evaluated conditions.
