Three 18(4→3)-abietanoids, a new natural product and two new compounds, named tripordolides A⁻C (⁻), were isolated from the leaves of Their structures were elucidated on the basis of their spectroscopic analysis, and the absolute configuration of compounds was confirmed by CD and X-ray crystallographic analysis using anomalous scattering of Cu α radiation. Compounds and showed moderate inhibitory activities against NO production in lipopolysaccharide-induced (LPS) RAW 264.7 macrophages in vitro.
