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 1α,6β-diacetoxy-8,13-epoxylabd-14-en-11-one, 1α-hydroxy-6β,7β-diacetoxy-8,13-epoxylabd-14-en-11-one, and 1α,9α-dihydroxy-6β,7α-diacetoxy-8,13-epoxylabd-14-en-11-one on the basis of spectral data.
