Outline of Final Research Achievements

Genetic and chemical analyses followed by pharmacological study were performed on botanical sources of several crude drugs, which have been collected through the field investigations in Mongolia, Myanmar and China. Gentiana macrophylla and Saposhnikovia divaricata from Mongolia were found to be with equivalent or superior quality to Chinese Gentiana Macrophylla Root and Saposhnikovia Root and Rhizome, respectively. Two Salacia species from Myanmar had potential to be resource of functional food. Chinese Drynaria Rhizome showed memory-improvement effect in a mouse model of Alzheimer’s disease, and naringenin was identified as bio-effective metabolite. Chinese Plantago Seed inhibited paclitaxel-induced mechanical allodynia in mice, and aucubin and pedicularis-lactone were identified as active constituents. These findings will lead to promote the production of each crude drug in their producing countries.
