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{mu}g/ml) were detected and SOD-like activity was inhibited up to 95%;at;500{mu}g/ml in supercritical extraction. To evaluate the whitening effect, tyrosinase inhibitory activity was conducted 89% of tyrosinase inhibitory effect examined at 1,000;{mu}g/ml. From these results, we suggest that the supercritical extracts from Curcuma longa L. is useful for cosmetic ingredients.
