A New Diterpenoid from Sheareria nana

摘要

One novel diterpenoid with a clerodane-type skeleton was isolated from the EtOH extract of Sheareria nana S. Moore, an annual composite plant distributed in South China. Its structure was elucidated to be 15,16,17-trihydroxyneo-clerodan-3,13-(~(Z))-dien-4-formyl by spectroscopic methods and the compound was named shearerianin.
