As a series of study on the evaluation of Alismatis Rhizoma and the chemical characterization of the processing, a quantitative method by high performance liquid chromatography (HPLC) for ten triterpene constituents, alisols A, A monoacetate, B, B monoacetate, E 23-acetate, F, and G and 13,17-epoxyalisol A, 11-deoxyalisols B and B 23-acetate, has been developed. By the use of this HPLC method, the contents of these triterpenes in various Alismatis Rhizoma and the fresh rhizoma of Alisma orientale JUZEPC. originaed from in China, Taiwan, and Japan were examined. Furthermore, the chemical change of the triterpene constituents during the drying process of the rhizoma of Alisma orientale has been investigated and it was found that the bioactive triterpenes of Alismatis Rhizoma such as alisol A and alisol A monoacetate were artificially formed during the drying process.
