title: Three new diterpenoids from Coleus forskohlii Briq.
abstract: Three new diterpenoids, forskolin G(2), forskolin H(3), forskolin I(4), were isolated from the whole plant of the Coleus forskohlii Briq., and their structures were elucidated as 1alpha,6beta-diacetoxy-8,13-epoxylabd-14-en-11-one, 1alpha-hydroxy-6beta,7beta-diacetoxy-8,13-epoxylabd-14-en-11-one, and 1alpha,9alpha-dihydroxy-6beta,7alpha-diacetoxy-8,13-epoxylabd-14-en-11-one on the basis of spectral data.
