Abstract:

Two new ent kauranoids, tenuifolin A (3β,6α,15β-trihydroxy-1α,7β-diacetoxy- 11β,16β-epoxy-ent-kaurane) (1) and tenuifolin B (1α,6α,11β-trihydroxy-3β, 7β-diacetoxy-ent-kaur-16-en-15-one) (2), together with four known compounds were isolated from the aerial parts of Isodon tenuifolia (W. W. Smith) Kudo collected from Zhongdian County, Yunnan Province, China. Their structures were determined by the spectral methods (including 2D NMR techniques).
