Abstract
Three new diterpenoids, gesneroidins D-F, together with the known diterpenoids, rabyuennane A and 3-acetylcalcicolin A, were isolated from Isodon gesneroides. Their structures were determined using a combination of one- and two-dimensional NMR techniques as 3β, 7β, 11β, 15β- tetraacetoxyl-ent-kaur-16-en-6-one; 15β-hydroxy-1α, 3β, 6α, 7β, 11β- pentaacetoxyl-ent-kaur-16-ene; and 6α, 11β-dihydroxyl-3β, 7β-diacetoxyl- ent-kaur-16-en-15-one.
