Abstract:
A novel bisnorkaurenic acid-type diterpenelactone, named mikanialactone (1), was isolated along with five known kaurenic acid-type diterpenes (2-6) from the aerial parts of Mikania hirsutissima DC (Compositae). The structure of the new bisnorditerpene was determined by spectroscopic means.
