title: ent-Atisane and ent-kaurane diterpenoids from Isodon rosthornii.
abstract: A new ent-atisanoid (1) and three new ent-kauranoids (2-4) belonging to different types, along with four known compounds were isolated from Isodon rosthornii. Their structures were established by means of extensive spectroscopic analysis. The absolute configuration of 1 was further determined by X-ray diffraction. Compounds 1 and 5 are the first example of atisane-type diterpenoid from this plant.
