摘要:
Three new dimeric prenylated C-6-C-3 compounds, namely, illicidiones A (1), B (2), and C (3), were isolated from the stem bark off 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.
