Three new dimeric prenylated C6–C3 compounds, namely, illicidiones A (1), B (2), and C (3), were isolated from the stem bark of Illicium oligandrum. The structure and absolute configuration of these compounds were determined by extensive spectroscopic and chemical analyses, including NMR, modified Mosher method, and single-crystal X-ray study. Compounds 1–3 exhibited weak anti-inflammatory activities.
