Six experimental stages were designed in our procedure, those are:(1) metabolite recovery and tested sample preparation: the metabolites were recovered by Amberlite XAD-2 absorption, followed by MeOH elution and solvent concentration;(2) antioxidant detection and strain selection: samples were quantitatively analyzed by the inhibition effects on formation of lipid peroxides and TBARS to screen the strains able to produce antioxidants. According to the established screening methods, we chose out a strain of actinomycetes, designed as AMBL-029C;(3) antioxidant purification: the fermentation broth was recovered by a series of separation techniques including centrifugation, Amberlite XAD-2 absorption, followed by MeOH elution and a successive TLC purification. The resulting primary purified compound [temperately designed as AMBL-029C-TS] was further analyzed by HPLC to monitor its purity;(4) physical-chemical characteristics: judging from the acid-base fractionation experiments, and the pH and temperature stability tests, the compound was deduced to be a acidic compound with the properties of low polarity and highly pH and temperature stable;(5) mechanism of the antioxidant: in comparison with some other known antioxidants, TS was subjected to investigate its antioxidant mechanism, together with BHT,-tocopherol, as well as two streptomyces metabolites, homogentisic acid and -phenylpyruvic acid, which were previously isolated as the natural antioxidants in our laboratory.
