摘要：

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 6 beta, 11 alpha -dihydroxy-16 alpha -methoxymethyl-6,20-epoxy-6,7-seco-ent-kaur-15-one-1,7-olide and 3 beta -acetoxy-6 beta ,11 alpha -dihydroxy-16 alpha -methoxymethyl-6,20-epoxy-6,7-seco-ent-kaur-15-one-1,7-olide, respectively, on the basis of detailed spectroscopic analyses.
