阿波藍に含有される有用微量成分の有効利用に関する研究

This study is aiming at development of the synthetic methods of the active fine ingredients containing in Awa indigo Plant (Awa-ai). The long tradition of the indigo dyeing is prevailing over a thousand year here in the Tokushima Prefecture, and historically the Ai-leaf had been sold in Kansai area about 550 years ago. Although our concern on the Ai-leaf used to be centered on a dyeing stuff, several biologically active ingredients have been reported recently contained in the Awa Indigo Plant. We have, therefore, been interested in these fine ingredients and here wish to develop the efficient and ecofriendly synthetic methods of such remarkable ingredients. The synthetic methods reported here are the methods activated by microwave (MW) irradiation and photoirradiation of the ultraviolet light (UV).
