摘要

Two new 19-oxygenated ent-kaurane diterpenoids, pharicinins D and E (1 and 2), together with an artifact, pharicinin D acetal (3) were isolated from the leaves of Isodon pharicus. Their structures were determined by 1D and 2D NMR spectroscopic analysis. All of them were evaluated for their cytotoxicity.
