摘要：
Two new diterpenoids, maoecrystal U and epi-maoecrystal P were isolated from the leaves of Isodon eriocalyx. Their structures were determined as 6 beta-acetoxy-15 beta-hydroxy-3 alpha, 20epoxy-ent-kaur-16-ene-1,7-dione 1 and 16 (s)-methoxymethyl-6 beta,7 beta-dihydroxy-7 alpha,20-epoxy-ent-kaur-2,3-ethenylene-1, 15-dione 2 respectively, by spectroscopic methods.
