ResumoThe study was conducted to investigate functional materials as skin whitening and anti-inflammatory agent from Taraxacum officinale and Taraxacum coreanum. The total polyphenol and flavonoid content in the ethanol extract of Taraxacum officinale were found to be 64.07㎎/g and 32.46㎎/g, respectively. In tyrosinase inhibitory activity, the hot water extract of Taraxacum coreanum was higher than the other extracts. However, in nitric oxide (NO) scavenging ability, the ethanol extract of Taraxacum coreanum was higher than the other extracts. the ethanol extract of Taraxacum coreanum showed strong NO production inhibitory effect in lipopolysaccharide (LPS)-stimulated Raw 264.7 cell. In the cell viability measurement by MTT assay and the lactate dehydrogenase (LDH) assay against L929 cell, the extracts were exhibited fine cell viabilities and normal LDH release levels as nontoxic result in sample concentration of 250~1000 ㎍/㎖. As a result, the ethanol extract and the hot water extract of Taraxacum coreanum could be applicable to functional materials for anti-inflammatory and skin whitening related fields, respectively.
