Abstract

One new phenolic glycoside (1) and one new benzofuran derivative (2) were isolated from the leaves of Illicium dunnianum. The structures of these compounds were established by using comprehensive spectroscopic data analysis, including the 1D and 2D NMR, IR, HR-ESI-MS, electronic circular dichroism and comparison with literature data. All isolates were evaluated for the inhibition against the production of NO by LPS-stimulated RAW 264.7 macrophages.
