对发酵液抑菌成分的研究表明，抑菌活性成分组成为挥发油倍半萜、酚和有机酸等类化合物，采用硅胶柱层析对发酵液抑菌活性部位进行分离实验，得到了6个具有明显抑菌活性的粗组分（组分1、2、3、8、9、10），其中组分1、2、3含有倍半萜类物质，组分8、9含有酚类物质，组分10中有含酚羟基的羧酸类物质。

All the compounds were isolated and identified from the bituminous coals for the first time, bis(2-ethylheptyl) terephthalate and 18-ethyl-17-(hexan-2\'-yl) docosanoic acid are new compounds.Further more, a Colourless Oil Liquid, a white acerate crystals containing some alkanes, a white tabular crystals consisting of some fatty acid esters and a white powder crystals in which some fatty acids exist were isolated and analysed by GC/MS for the first time.Through this research, a study method of"classification extract of bituminous coal- separation with silica-gel and gelatin column chromatographies- identification of the isolated compounds by FTIR, GC/MS, LC/MS, 1H NMR and 13C NMR analyses"was established and proved to be a practical approach toward separable and non-destructive identification of some organic compounds in bituminous coals for coal chemistry research.
