ABSTRACT
The antibacterial and antifungic activities of two kaurenic acids, ent kaurenoic acid and cinnamoylgrandifloric acid isolated from a hexane extract of aerial parts of Mikania laevigata, were investigated and compared with the activities of other kaurenic acid-derivatives substituted on carbon-15. Only acetylgrandifloric acid (en-kaur-16-en-15 alfa-acetyloxy-19-oic) and its epimer xylopic acid (ent-kaur-16-4n-15 beta-acetyloxy-19-oic) displayed significant antibacterial activity at concentrations >=250 microng/ml., the 15 alfa epimer being the most active
