Abstract
19,28-epoxy-24-nor-18 alpha-oleanane (1) has been identified in the Am auligak and Hammerhead crude oils by comparison with an authentic stan dard prepared from betulin. The biological origin of this novel biomar ker is likely to be 23-hydroxybetulin (10). (C) 1998 Elsevier Science Ltd. All rights reserved.
