On the basis of chemical and spectroscopic evidence, the structure and absolute configuration of lasiokaurin and lasiodonin, which were isolated from Isodon lasiocarpus (HAYATA) KUDO, were established as ent-7β, 20-epoxy-1β-acetoxy-15-oxo-16-kaurene-6α, 7α, 14α-triol (II) and ent-7β, 20-epoxy-15-oxo-16-kaurene-1β, 6α, 7α, 11α-tetraol (VIII), respectively.
