Abstract
A study of hopanoids in the sediments of five European lakes has identified bacteriohopane-32,33,34,35-tetrol, 35-methoxybacteriohopane-32,33,34-triol and two new hopanoids with shorter side chains: 35-norbacteriohopane-32,33 ,34-triol and 33,34,35-trinorbacteriohopane-31,32-diol. Their structures ha ve been revealed by mass spectrometry. Polyfunctionalised hopanoids with sh ortened side-chains are not often reported in sediments, mainly due to the analytical procedures used. Their systematic investigation could shed furth er light upon the early diagenesis of biohopanoids. (C) 1999 Elsevier Scien ce Ltd. All rights reserved.
