A novel clerodane-type diterpenoid, with the trivial name shearerin A, was obtained from the EtOH extract of Sheareria nana S. Moore. Its structure was elucidated as 15,16,17,18-tetrahydroxy-neo-trans-clerodan- 3,13-(Z)-dien by spectroscopic methods, including ESI-MS, HR-ESI-MS, and 1D NMR and 2D NMR.
