- 中文摘要: Two new diterpenoids, Maoecrystal U and epi-maoecrystal P, together with nine known diterpenoids and eight other known compounds were isolated from Isodon eriocalyx. The structures of two new diterpenoids were elucidated as 6-acetoxy-15-hydroxy-3,20-epoxy-ent-kaur-16-ene-1,7-dione and 16(S)-methoxymethy-6,7-dihydroxy-7,20-epoxy-ent-kaur-2,3-ethenylene-1,15-dione on the basis of spectroscopic evidence, especially by 2D NMR techniques.
