Abstract
Two enmein type diterpenoids, taibaijaponicains A and B, were isolated from the ethanol extract of the leaves and branches of Isodon japonica. Their structures are designated as 6beta,11alpha-dihydroxy-16alpha-methoxymethyl-6,20-epoxy-6,7-seco-ent-kaur-15-one-1,7-olide and 3beta-acetoxy-6beta,11alpha-dihydroxy-16alpha-methoxymethyl-6,20-epoxy-6,7-seco-ent-kaur-15-one-1,7-olide, respectively, on the basis of detailed spectroscopic analyses.Entities:
