Abstract
The present study was conducted in order to evaluate the effects of blanching on the total and individual phenolic and antioxidant activities of 4 young sprouts of medicinal plants: dureup (Aralia elata), caster aralia (Kalopanax pictus), tree-of-heaven (Cedrela sinensis), and ogapi (Acanthopanax sessiloflorus). Caster aralia and dureup displayed significant reduction of Fe2+ chelation following blanching, but no alteration of DPPH or ABTS radical scavenging activity. Blanched ogapi displayed lower Fe2+ chelation as well as decreased DPPH and ABTS radical scavenging activities compared to raw sample. In contrast, tree-of-heaven displayed significantly increased antioxidant activity after blanching. Major phenolic compounds in mountain vegetables were chlorogenic acid and vanillic acid. In particular, chlorogenic acid contents increased by 11.2-68.1% in all vegetables except for ogapi after blanching. The results of this study show that blanching might be a useful tool for improving the beneficial properties of tree-of-heaven.
