The root of several Paeonia species is one of the most frequently used plant materials in traditional Chinese medicine, and has been shown to have a variety of pharmacological properties. Owing to the differences in species, cultivation, harvesting and processing, the quality of the roots as commercial medicinal herbs varies to a considerable extent. A quantitative high performance liquid chromatographic method has been developed for the quality evaluation of Paeonia root, and a number of commercial samples have been examined. A quantitative 1 H‐nuclear magnetic resonance procedure has also been developed for this purpose, and this may find a wider application in the analysis of other plant materials.
