추출조건에 따른 울금의 항산화 및 미백 효과

Abstract

Curcuma longa L. of Zingiberaceae family, has been reported to have radical scavenging activity and antiinflammatory effect. On these facts, biological activity and whitening effect were examined to evaluate a bioactivity of the extracts of Curcumma longa L. by extraction conditions as a possible pharmaceutical material. When compared extraction methods, supercritical extraction was the best showing various biological activities and whitening effect. The highest electron donating ability (89% at 1,000 ㎍/㎖) were detected and SOD-like activity was inhibited up to 95% at 500 ㎍/㎖ in supercritical extraction. To evaluate the whitening effect, tyrosinase inhibitory activity was conducted 89% of tyrosinase inhibitory effect examined at 1,000 ㎍/㎖. From these results, we suggest that the supercritical extracts from Curcuma longa L. is useful for cosmetic ingredients.
