Abstract

|
|
In this study, we investigated the antioxidative activity and inhibitory effects on elastase and tyrosinase of Persicaria hydropiper L. extracts. The free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activities () of ethyl acetate fractions of Persicaria hydropiper L. was . Reactive oxygen species (ROS) scavenging activities () of some Persicaria hydropiper L. extracts on ROS generated in -EDTA/ system were investigated using the luminol - dependent chemiluminescence assay. The ROS scavenging activities () of ethyl acetate fractions of Persicaria hydropiper L. was . The protective effects of extract / fractions of Persicaria hydropiper L. on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The Persicaria hydropiper L. extracts suppressed photohemolysis in a concentration dependent manner (). Inhibitory effects () on tyrosinase of aglycone fraction of Persicaria hydropiper L. extracts was . Inhibitory effects () on elastase of aglycone fraction of Persicaria hydropiper L. extracts was . These results indicate that extract / fractions of Persicaria hydropiper L. can function as antioxidants in biological systems, particularly skin exposed to UV radiation by anti-oxidative activity and protect cellular membranes against ROS. Persicaria hydropiper L. extract / fractions could be used as a new cosmeceutical for whitening and anti-wrinkle products.
