The structures of all four compounds were determined by spectrometric analysis. The new clerodane diterpene and (-)-hardwickiic acid contain structural features that are completely different from the highly oxygenated casearins and casearvestrins isolated from C. sylvestris.1100-1103eng15-hydroxy-3-cleroden-2-oneCasearia sylvestrisClerodane diterpenesArtigo10.1590/S0100-40422007000500009S0100-40422007000500009WOS:000249501000009Acesso aberto2-s2.0-361489906442-s2.0-36148990644.pdf44840836852516732518006820764120
