摘要：

Three new diterpenes were isolated from the aerial part of Haplopappus chrysanthemifolius and assigned the structures 6 alpha-hydroxy-ent-labd-8(17)-en-15-oic acid, 3 beta-acetoxy-ent-labd-8(17)-en-15-oic acid and 18a-acetoxylabd-8(17)-en-15-oic acid. The structures were elucidated by high field NMR spectroscopy. (C) 1999 Elsevier Science Ltd. All rights reserved.
