摘要：

3 beta-Hydroxy-5 alpha-androstan-17-one (epiandrosterone), 5 alpha-androstan-3,17-dione, 3 alpha-hydroxy-5 alpha-androstan-17-one (androsterone), 5 alpha-androstan-3 beta,17 beta-diol and 5 alpha-androstan-3 alpha,17 beta-diol have been identified in the solvent soluble fraction of peat from Bolton Fell Moss (Cumbria, U.K.). The structures and delta(13)C values of these androstane derivatives indicate a diagenetic origin in sterols also present in the peat and provide the first evidence that cleavage of the C-17 side-chain can occur during early diagenesis, microbial oxidation being the most likely mechanism.
