Summary:The occurrence, distribution and degradation pathways of hopanoid triterpanes were studied in 13 French soil samples with varying degrees of biological activity. Hopanoids were shown to occur in all samples, suggesting that they are ubiquitous not only in subaquatic sediments, but also in soils. Hop-22(29)-ene was generally predominant in the hydrocarbons, whereas the 17 beta H,21 beta H-bishomohopanoic acid (C32) was the major component in the acids. The concentrations of hopanes were usually rather low, except in acidic peat. The distribution in carbon number of hopanes and hopanoic acids shows great similarities with those of moderately oxic subaquatic sediments. Intact bacteriohopane tetrol, widespread in microorganisms and the main precursor of geohopanoids, was identified in substantial amounts in a peat exposed to groundwater oscillations.
