In each column, values with different letters are statistically different (P ≤ 0.05).

TAC: total antioxidant activity (μg ISE mg⁻¹), TRP: total reducing power (μg AAE mg⁻¹), FRSA: free radical scavenging activity (% of DPPH inhibition), TPC: total polyphenol content (μg GAE mg⁻¹), and TFC: total flavonoid content (μg QE mg⁻¹).
