title: New sesquiterpenes from Ligularia macrophylla.
abstract: From the roots of Ligularia macrophylla, a bisesquiterpene, ligumacrophyllal (1), and an eremophilane sesquiterpene, ligumacrophyllatin (2) were isolated. Their structures were elucidated by 2D-NMR herein. Additionally, seven known compounds (3-9) were afforded from the plant, and compound 3 was found as natural product for the first time.
