A new norditerpenoid lactone from the seeds of Podocarpus nakaii

摘要

A new norditerpenoid lactone, nakaiilactone A was isolated from the seeds of Podocarpus nakaii together with a known one, nagilactone C and a known bisnorditerpenoid lactone, inumakilactone B. The structure of the new compound was determined by detailed analyses of the spectroscopic data, especially 1D- and 2D-NMR and HR-ESI-MS.
