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).
