Abstract

We compared antioxidant activity and biological compounds of ginseng root extractions between ultrasound (US) and microwave extraction (ME). The maximum total ginsenoside content of ginseng root extraction was 27.53mg/g under the ultrasound conditions of 60?"? for 2h (50 kHz, powder 250W). It was higher than ME processing (23.74mg/g) under the condition of powder 300W for 8min. Moreover, the ginseng root extraction by US2 contained more total polyphenol (11.51mg/g) and flavonoid (13.37mg/g) than ME2 treatment. Moreover, the ginseng root extractions of UE treatment showed more powerful scavenging activities against DPPH, ABTS radicals and higher FRAP activity. Scanning electron microscopic (SEM) images of the ginseng root tissue with US and ME processing provided visual evidence of the disruption effect. The US procedure used for ginseng root processing contributed to enhance extraction efficiencies and antioxidant activity of functional materials.
