Direct vs indirect ultrasound-assisted extraction of phenolics from wild sumac (Rhus tripartita): Optimization by Response Surface Methodology (RSM) and LC-MS profiling.

ABSTRACT: This study explores the potential of wild sumac (Rhus tripartita) fruits as a rich source of antioxidants. To achieve this, two ultrasound-assisted extraction (UAE) techniques-indirect (IUAE) and direct (DUAE)-were employed under predefined conditions to optimize antioxidant recovery. The extraction parameters for each method were investigated using response surface methodology (RSM) and Box-Behnken Design (BBD), focusing on three key factors for each method. The total phenolic content, quantified by the Folin-Ciocalteu method (TP-FC), was defined as the response variable. TP-FC values ranged from ∼ 6 to ∼ 12 mg GA eq./g DW for IUAE, and from 11 to 30 mg GA eq./g DW for DUAE. Quadratic models were developed and the determination coefficients exceeded 0.9 for both methods, confirming models
