Abstract: Objective:To evaluate the content and antioxidant activity of the total phenolic from Chirita longgangensis var.hongyao.Methods:Different polarity solvent and extraction methods were attempted for the extraction of the total phenolic from Chirita longgangensis var.hongyao in this investigation.Folin-Ciocaileu method was developed for evaluation of the total phenolic content of extracts.The antioxidative activity of total phenolic was determined by the capacity of scavenging 1,1-diphenyl-2-picrylhydrazyl（DPPH） free radical,and the evaluated unit was expressed as the equivalent concentration of ascorbic acid.Results:The content of total phenolic and antioxidant activities of n-butanol extraction and soaking methods was the highest,respectively;the efficiency increased with the content of total phenolic extracted from plants.Conclusion:The extracts owned obvious antiradical capacity.
