Natural Product Identification
Common NameCarnosic acid
DescriptionCarnosic acid, also known as carnosate, belongs to the class of organic compounds known as diterpenoids. These are terpene compounds formed by four isoprene units. Carnosic acid is found in Hypis dilatata, Lepechinia hastata, Lepechinia salviae, Nocardia sp. NRRL5646, Rosamarinus officinalis, Salvia aurea, Salvia apiana, Salvia canariensis, Salvia columbariae, Salvia mellifera, Salvia munzii, Salvia pachyphylla and Salvia tomentosa. Carnosic acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
