A new ent-kauranoid from Isodon lophanthoides var. geradianus.
A new ent-kaurane diterpenoid, lophanthodin G (1) and one known abietanoid, 6alpha-hydroxyferruginol (2), were isolated from the leaves of Isodon lophanthoides var. geradianus. The structure of the new compound 1 was established using spectroscopic methods including extensive 1D and 2D NMR analysis.
