Antioxidant components and antioxidant activity of free ethanolic extracts (control) and microcapsules powders encapsulated with Treatment A (T_A), Treatment B (T_B), Treatment C (T_C), and Treatment D (T_D) by freeze drying. Results expressed as 3n ± S.D. TPC based on calibration curve of gallic acid, expressed as mg gallic acid equivalents (GAE) per gram of dry extract; r = 0.993. TFC expressed as mg quercetin equivalents (QE) per gram of dry extract; r = 0.9891. TCT content based on calibration curve of (+)-catechin, expressed as mg catechin equivalents (CE) per gram of dry extract; r = 0.991. The values β-carotene bleaching assay of selected extracts (mg/mL) based on percent bleaching inhibition. CUPRAC of selected fungal extracts (mg/mL) based on absorbance (λ450 nm). EC₅₀ values (mg/mL) is representative of the effective concentration at which 50% of Fe²⁺/Cu²⁺ ions were chelated. **** Very extremely significant (p-value < 0.00001), *** extremely significant (0.00001 < p-value < 0.0001), ** very significant (0.0001 < p-value < 0.001), significant (0.001 < p-value < 0.01), and ns not significant
