摘要
Two new diterpenoids, forskolin G and H were isolated from the chloroform extract of the roots of Coleus forskohlii, and based on spectroscopic data, their structures were identified as 1a-hydroxy-6b,7b-diacetoxy-8,13-epoxylabd-14-ene-11-one (1), and 1a,6b-diacetoxy-8,13-epoxy labd-14-ene-11-one (2), respectively.
