Abstract
From the leaf surface exudate of the aerial parts of Salvia cinnabarina a new secoisopimarane diterpenoid with a non-specific spasmolytic activity on histamine-,
acetylcholine-, and barium chloride-induced contractions in the isolated guinea-pig
ileum was obtained. The IC50 value obtained was comparable with that obtained for papaverine. The structure of
3,4-secoisopimara-4(18),7,15-triene-3-oic acid was established by 1D and 2D NMR spectroscopic
techniques.
