Abstract
A new abietane diterpenoid, gerardianin A (1), along with a known compound 6,7-dehydroroyleanone (2), has been isolated from the aerial parts of Isodon lophanthoides var. gerardianus [Bentham] H. Hara. The structure of 1 was determined on the basis of spectroscopic methods and X-ray single-crystal diffraction analysis.
