Two extraction techniques, automatic soxtherm apparatus and conventional ultrasonic extraction, were compared in terms of yield, composition, and with special focus on antioxidant activity. In the DPPH test automated extraction showed higher antioxidant potential with IC50 value of 7.5 mg/mL as compared to that of ultrasonic extraction which is 12.5 mg/L, whereas combining both was found to be relatively better. A similar trend in total phenolic and total flavonoid contents was observed. HPLC analysis of both extracts revealed the presence of gallic acid, p-hydroxybenzoic acid, caffeic acid, syringic acid rutin, and ferrulic acid with significant difference in their profile.
