- 中文摘要: The isolation of the antibiotic produced by Streptomyces fimicarius 007 was carried out by extracting the culture filtrate with ethyl acetate followed by evaporating off the solvent. The crude antibiotic thus obtained, after extraction with petroleum ether, was dissolved in benzene and chromatographed through alumina column with a mixture of acetone and benzene as effluent. The crystalline antibiotic was obtained from the acetone solution by gradual addition of petroleum ether. The purified product crystallized in vermillion platelets. Its alcoholic solution showed strong absorption bands at 450-454mμ and 232-241mμ. The properties of this antibiotic was found to be very similar to those of actinomycins. It is surmised that the antibiotic might be a kind of actinomycin.
