A New Antibacterial Diterpene from the Roots of Salvia caespitosa
Abstract From the roots of Saliva caespitosa Montbret and Aucher ex. Bentham a new diterpene 6β-hydroxyisopimaric acid (1) has been isolated together with four known diterpenes, one new triterpenoid, 3-acetylvergatic acid (2), as well as five known triterpenoids, two steroids and a flavone. The structures of the compounds were established by spectroscopic analyses. The isolated compounds were tested against standard bacterial strains. Only the new diterpene, 6β-hydroxyisopimaric acid has strong activity (MIC 9μg/ml) against S. aureus and (MIC 18μg/ml) against S. epidermidis as well as against B. subtilis (MIC 9μg/ml).
