Physiological Activity of Equisetum arvense Fertile Stems Extracts as Beauty Materials

Abstract

The water and 70% ethanol extracts of Equisetum arvense fertile stems were carried out to investigate the whiting, anti-wrinkle and physiological activity of the possibility as a cosmetic material. The contents of soluble protein of water and ethanol extract were determined as 21.96 mg/g and 23.07 mg/g, respectively. The reducing sugar contents of water extract contained 147.54 mg/g and ethanol extract contained 108.83 mg/g. The contents of flavonoid and polyphenol compound of water extract were 28.45 mg/g and 22.36 mg/g, that of ethanol extract were 28.25 mg/g and 26.72 mg/g, respectively. The tyrosinase inhibition activities of both extracts were less than 10% inhibition. The collagenase and xanthine oxidase inhibition of water extract were 18.86% and 33.82%, that of ethanol extract were 24.96% and 37.25% at 1.0 mg/mL. The electron donating ability of water extract was 94.60% and that of ethanol extract was 87.21%, respectively. In the analysis of nitrite scavenging ability of pH 1.2 condition, ethanol extract (64.44%) showed a significantly higher effect than water extract (43.51%). The SOD like activity of water and ethanol extract showed less than 17% at 1.0 mg/mL concentration. This suggest that the ethanol extract of E. arvense fertile stems have the potential to be used as physiological activity source for the beauty food and cosmetic material.
