Abstract Objective:This paper mainly herbal extracts Shenjin grass Acid oxidation. Stone Pinaceae Shenjin grass as raw materials to extract the acid solution huperzine. Absorbance value of both indicators of different concentrations of huperzine A on pyrogallol self-oxidation and inhibition of oxygen free radicals produced by hydroxyl radical produced by Fenton method the absorbance of the impact, according to two kinds of free radicals different concentrations under the influence of Huperzine A, the absorbance changes in the slope calculation within 5min of Huperzine A on oxygen radicals and hydroxyl radical scavenging. The results showed that huperzine A in different antioxidant system showed strong oxygen radical and hydroxyl radical scavenging effects, the results of this study the clinical application of Shenjin grass and further development of its antioxidant function provides some basis.
