从巩县风化煤中提取的黄腐酸(FA)在人体和动物体中显示出较明显的生理和药理作用。为此,我们曾对这种FA进行了较细致的结构表征。从所得的结果来看,它与吐鲁番风化煤FA在结构上有一定的差别。本工作采用色谱/质谱(GC/MS)直接
Fulvic acid (FA) extracted from weathered coal in Gongxian County shows obvious physiological and pharmacological effects in human and animal body. For this reason, we have conducted a more detailed structural characterization of such FA. From the results obtained, it is with the Turfan FA weathered coal in the structure of certain differences. This work uses chromatography / mass spectrometry (GC / MS) directly
