Three new diterpenoids from Coleus forskohlii Briq.
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.
