Fund Project: The research was supported by a grant of the Biogreen 21 program (2006), Rural Development Administration, Republic of Korea. We are grateful to the Korea Basic Science Institute (KBSI) for supplying the NMR spectra.

A new diterpenoid, named populusol A (1), was isolated from the methanolic extraction of the stem bark of Populus davidiana. The structure was elucidated on the basis of extensive 1D and 2D NMR as well as HRFAB-MS spectroscopic analysis.
