Abstract: Additional two compounds have been isolated from the stems and leaves of Isodon nervosus (Hemsl.) Kudo. On the basis of spectral analysis combined with preparation of derivative, compound 4 was identified as em-lα, 6β, 7β, llα, 15β-pentahydroxy-7α, 20-epoxykaur-16- ene(nervosin D). It was a new diterpenoid derived from nature plant for the first time. Compound 8 was identified as 2α-hydroxy ursolic acid. It was a known compound obtained for the first time.

Key words: lsodon nervosus, Nervosin D, 2α-hydroxy ursolic acid, Diterpenoid
