Tetrahymanol has been identified in several sediment samples from different depositional environments by gas chromatography-mass spectrometry and by coinjections with an authentic standard. Together with literature data this shows that tetrahymanol is likely to be widespread, which is in accordance with the ubiquitous occurrence of its presumed diagenetic product, gammacerane, in more mature sediments and crude oils. The diagenetic conversion of tetrahymanol to gammacerane most likely proceeds via dehydration and subsequent hydrogenation. The intermediate in this conversion, gammacer-2-ene, has been synthesized, and its presence in one sample confirmed by coinjections. The identification of tetrahymanol in marine sediments indicates either that protozoa of the genus Tetrahymena are widely distributed or that tetrahymanol is also a natural product of organisms other than Tetrahymena .
