Outline of Final Research Achievements |
In this study, we performed identification and functional analysis of Ca2+ signaling inhibitor derived from edible Asteraceae plants. Three compounds were isolated from Petasites japonicus and Cacalia delphiniifolia. Bakkenolide B isolated from Petasites japonicus inhibited production of interleukin-2, a cytokine which is involved in atopic dermatitis, in human T cell line Jurkat. Additionally, the individual component analysis of Petasites japonicus, Cacalia delphiniifolia, and Cacalia hastata clarified the qualitative and quantitative diversity of their main components.

Academic Significance and Societal Importance of the Research Achievements |
本研究課題で対象とした「山菜」は、重要な伝統食資源であり、和食文化や地域文化・地域産業において重要な役割を担っているが、その健康機能性については未解明な部分が多い。本研究により、このような学術的知見が乏しい現状にある山菜について、新たな機能性成分が見出された。またこの知見は、機能性素材としての有用性を示すものであり、山菜の高付加価値化に繋がるものと考えられる。
