摘要：

Lipid extracts from two acidic hydromorphic soils contained simple lipids and a slightly soluble fraction (named polar fraction or complex lipids). Ether- and ester-bond cleavage and KMnO4 oxidation of the polar fraction was followed by GC-MS analyses of the released compounds. In contrast to n-alkanols and alpha,-omega-diacids, normal monoacids were found to be the same as in simple lipids. It is concluded that the polar fraction of the soil corresponds to highly aliphatic macromolecules with a polyethylene-like structure, in which some simple lipids may be incorporated to form a protokerogen.
