Two new diterpenoids were isolated from the ethyl acetate soluble fraction of Stachys parviflora.
The structure elucidation of the compounds 1 and 2 were carried out by advanced spectroscopic analysis.
These new diterpenoids 1 and 2 showed marked attenuation of castor oil induced diarrhea.
Diterpenoids 1 and 2 could be useful antidiarrheal agent.
