Abstract

A new xanthone, allanxanthone F (1), and 10 known compounds were isolated from the ethanol extract of Garcinia bracteata. The structure of compound 1 was elucidated based on spectroscopic methods (UV, IR, HR-ESI-MS, and NMR). In addition, compounds 1–9 were assessed for their anti-inflammatory activities based on the expression of nitric oxide (NO) levels on lipopolysaccharide (LPS)-induced RAW264.7 macrophages, and compounds 1–3, 4 and 6–9 suggested potential anti-inflammatory activities.
