摘要：

The phenolic diterpene carnosic acid appears to be the main substance for general oxidation leading to artifacts with gamma- or delta-lactone structure in extracts of Rosmarinus officinalis and Salvia officinalis. Until now it was only possible to prepare carnosic acid by hydrogenolysis of carnosol. A semipreparative HPLC method has been developed isolating carnosic acid among other phenolic diterpenes. The separated substances were identified by C-13-nuclear magnetic resonance (NMR), H-1-NMR, mass and IR spetroscopy. Conversion of carnosic acid and carnosol to other phenolic diterpenes was investigated by HPLC.
