The cloves are herbs with a refreshing and sweet scent. They include high amount of antioxidants such as polyphenols and are often used as tea ingredients, spices, and herbal medicines. In this study, we aimed to investigate the possibility of using cloves as a functional cosmetic material. Extract was obtained from dried flower buds of clove by heating clove-distilled water mixture (200 g/L) at 60℃ for 2 hours and then removing suspended solids by filtration. The total phenolic and total flavonoid contents in the extract were measured. The antioxidant capacity of extract was measured by DPPH and ABTS assay. The whitening potency of extract was determined by measuring tyrosinase inhibitory activity. To evaluate the anti-wrinkle ability, the inhibitory activities of collagenase and elastase were measured. The DPPH and ABTS+ radical scavenging activities were 73.9% at 9.7 g/L of extract and 100% at 0.1 g/L of extract, respectively. Tyrosinase activity was inhibited by 56.3% at 19.4 g/L of extract. In the presence of extract, collagenase and elastase activities were decreased by 88.2% at 19.4 g/L and 80.0% at 4.9 g/L, respectively. The result clearly shows that extracts have high antioxidant activity at a relatively low concentration, moderate whitening activity, and marked anti-wrinkle activity. The result demonstrates that water extract of clove can be used as a potential material for functional cosmetics.
