摘要(Abstract):

[Objectives] To study in vitro antioxidant activity of extracts from Eleutherine plicata Herb by different extraction methods.[Methods]1,1-diphenyl-2-picrylhydrazyl( DPPH) free radical scavenging method,2,2'-Azinobis( 3-ehtylbenzothiazolin-6-sulfnic acid) diammonium salt( ABTS) free radical scavenging method,and iron ion reduction ability determination method were applied to measure the extracts of Eleutherine plicata Herb by ethanol extraction,water extraction,and ethanol extraction after water extraction,and comparison was made with positive control Vc( vitamin C). [Results]The ethanol extract,water extract,and ethanol extract after water extraction of Eleutherine plicata Herb had a high DPPH free radical,ABTS free radical scavenging activity,and reducing activity. [Conclusions]E. plicata Herb is a natural antioxidant with high potential.
