  • Abstract This research regards 12 kinds of Chinese herbal spreading the goal of this research from ancient times as, hope to find out the result with anti-oxidant function. Except use the generally common anti-oxidant method of inspection:Ferrous ion chelating activity、DPPH radical scavenging activity、Reducing power, Increase the method to measure several kinds of free radicals newly:Ultra-weak Chemiluminescence,in detail one tells different efficiency in resisting the oxidation of various kinds of Chinese herbal medicines.
    Through the survey of six kinds of anti-oxidant experiments , prove that these 12 kinds of Chinese herbal all have anti-oxidant ability . It was the Mesona chinensis Benth that it had the best result that anti-oxidant in all samples, secondly it is leaf of the Nelumbo nucifera Gaertn、Salyia miltiorrhiza Bunge、seeds core of Nelumbo nucifera Gaertn、Curcuma aromatica Salisb (turmeric).No matter Ferrous ion chelating activity、DPPH radical scavenging activity、Reducing power Superoxide anion 、Hydroxyl radical and Peroxyl radical have a good result。And Liriope spicata Lour winter and Xihonghua,it is not good to reduce strength , Reducing power、DPPH radical scavenging activity、Superoxide anion 、Hydroxyl radical and Peroxyl radical ,even have no Ferrous ion chelating activity and ability to remove Peroxyl radical.And analysis with High performance liquid chromatography(HPLC), the Chinese herbal sample finding the anti-oxidant result with excellent result, all present the crest obviously.
