摘要：

From the resinous exudate of Haplopappus deserticola a new clerodane diterpene named deserticolic acid (1), the known 18-acetoxy-cis-cleroda-3,13E-dien-15-oic acid (2) and four flavonoids were isolated. The structure of 1 was elucidated as 19-hydroxy-cis-cleroda-3,13E-dien-15-oic acid (ent-5 alpha form) by spectroscopic methods. (C) 1999 Elsevier Science Ltd. All rights reserved.
