Implication

Optimization of sonotrode extraction increases phenolic content and antioxidant power in avocado leaf residues, suggesting potential nutraceutical benefits.

Key Points

The main aim is to optimize the extraction of phenolic compounds from avocado leaves using a sonotrode method.
Utilized a sonotrode at 60% amplitude and 10 minutes extraction time with 50% ethanol.
Employed Box-Behnken design and response surface methodology for optimization.
Compared phenolic extraction from 'Hass' and 'Fuerte' avocado cultivars using HPLC-ESI-TOF-MS and HPLC-FLD.
Achieved a 47-52% increase in total phenolic content and antioxidant activity from optimal conditions.
Identified 51 phenolic compounds, with 'Fuerte' having 1.7 times higher phenolics than 'Hass'.
Documented strong correlations between antioxidant activities and flavonoid/proanthocyanidin content.
