Abstract
A new pyrrolidinone diterpenoid, excisusin F (1), was isolated from the aerial parts of Isodon excisus (Lamiaceae), together with four known compounds, and their structures were determined mainly by NMR (1D and 2D) and mass spectrometry. Excisusin F (1) and inflexarabdonin E (3) showed potent inhibitory effects of LPS-induced nitric oxide production in RAW264.7 cells with the IC50 value of 10.4 and 3.8 μM, respectively.
