title: A new illicinolide from leaves of Illicium micranthum Dunn.
abstract: The ethyl acetate extract from leaves of Illicium micranthum Dunn exhibited radical scavenging ability on DPPH radical-scavenging assay. Further phytochemical investigation led to the isolation of a new sesquiterpenoid, illicinolide C (1), and eight known compounds (2-9). The structural elucidations of the compounds were based on spectroscopic methods and by comparison of their spectroscopic data with those reported in the references. Except compound 9, all the other compounds were isolated from I. micranthum Dunn for the first time, while compounds 1 and 2 were new to the Illiciaceae family.
