Elevation of anti-oxidative activity and inhibitory activities against tyrosinase, elastase, collagenase and hyaluronidase of oplismenus undulatifolius by elicitor treatment

This study was designed to assess the change of the antioxidative and biological enzyme activities [tyrosinase, elastase, collagenase, and hyaluronidase (HAase)] of extracts from elicitortreated Oplismenus undulatifolius. Elicitor-treated O. undulatifolius showed higher total phenolic content than the non-treated extract. As a result of comparing the anti-oxidant activity of elicitortreated O. undulatifolius extract and non-treated extract, the elicitor-treated group showed high activity. Elicitor-treated O. undulatifolius showed higher elastase and collagenase inhibitory activities as anti-wrinkle effect, tyrosinase inhibitory activity as whitening effect, and anti-inflammation effect to induced as HAase inhibition than the non-treated extract. Therefore, elicitortreatment during O. undulatifolius cultivation in outdoors will elevate total phenolics content in the plant and elevate of various bioactivities, which will yield high quality for industrialization.
