Three kinds of Allium hookeri including raw material, fermented extracts and cellulase treated fermentation extracts were tested to see possibility as functional cosmetic agent. Polyphenol and flavonoid concentration were measured, antioxidant, whitening, anti-wrinkle and antimicrobial activity were tested as cosmetic assays. Ethanol extract of Allium hookeri root contained 305μg/ml polyphenol. Antioxidant effect of Allium hookeri was lower. Ethanol extract of Allium hookeri root showed 70% tyrosinase inhibition at 500μg/ml. Fermentation generally increased elastase inhibition among Allium hookeri extracts. Fermented Allium hookeri dried root by Lactobacillus plantarum(FDRLP) and cellulase treated fermented Allium hookeri dried root by Lactobacillus plantarum(CFDRLP) indicated strong anti-wrinkle effect. CFDRLP indicated significant antimicrobial activity for E.coli and staphylococcus aureus. Stability test of skin including 0.5% Allium hookeri extracted indicated stable formulation for 28 days. In conclusion, fermented Allium hookeri extracts indicated strong anti-wrinkle effect with significant antimicrobial activity. It showed good possibility for functional cosmetic agent. |
