| Abstract;The dried rhizome of the aquatic plant Alisma orientale JUZEP. (Alismataceae) has been used as a Chinese natural medicine, Alismatis Rhizoma, which is prescribed for diuretic and anti-inflammatory purposes, and treatment of thirst in various Kampo medicinal preparations. In recent years, Chinese Alismatis Rhizoma has been imported and commonly used in Kampo medicine, due to the poor supply of Japanese Alismatis Rhizoma. In Japan, Chinese Alismatis Rhizoma is classified into two types named in Japanese as "Sentaku" (from Szechwan Province) and "Kentaku" (from Fukien Province) according to their regions of origin. This article deals with our recent chemical and pharmacological studies, which include the structures and biological activities on the sesquiterpene and triterpene constituents from Sentaku, Kentaku, and Japanese Alismatis Rhizoma. In addition, the changes of the terpenoid constituents during the drying process of the rhizome of Alisma orientale were investigated using quantitative method by HPLC and several bioactive sesquiterpenes and triterpenes were found to be artificially formed during the drying process.
