|
|
Objectives : In this study, anti-oxidant activity of Taraxacum platycarpum is confirmed to investigate cosmeceutical activity for utilization as a cosmetic ingredients.
Methods : In the anti-oxidant and whitening effect experiment, the electron donating ability of Taraxacum platycarpum extracts, their SOD-like activity, and the inhibitory activity of xanthine oxidase, tyrosinase were examined.
Results : Radical-scavenging activity of water and ethanol extract was examined using {alpha},{alpha}-diphenyl-{beta}-picrylhydrazyl (DPPH). Water and ethanol extract from Taraxacum platycarpum showed 62.9% and 54.7% at 500 ppm concentration in DPPH radical inhibition, respectively. In the test of superoxide dismutase (SOD)-like activity, water extract showed 63.4% at 1,000 ppm concentration, while ethanol extract showed 49% at 1,000 ppm concentration. In the test of xanthine oxidase inhibition, ethanol extract showed 66.8% at 1,000 ppm concentration. Tyrosinase inhibition effect related to whitening effect showed 36.3% and 54.2% in ethanol extract and water extract at 1,000 ppm concentration, respectively.
Conclusion : According to these results, it is possible that the extract of Taraxacum platycarpum can be used as a new natural material of cosmetic industry.
