摘要：

Two novel 28-noroleanane-derived spirocyclic triterpenoids with unusual skeleton structures, phlomisone (1), phlomistetraol A (2), were isolated from the roots of Phlomis umbrosa. Their structures were elucidated by spectroscopic methods, including 1D, 2D nuclear magnetic resonance (NMR), high-resolution mass spectrometry (HR-MS). (C) 2008 Pu Liu. Published by Elsevier B.
