Abstract (+)‐ and (−)‐Xanchryones F and G ((+)‐ and (−)‐ 1 and 2 ) were isolated from the plant Xanthostemon chrysanthus by chiral separation. Compounds 1 and 2 featured a new carbon skeleton with cinnamoyltriketone‐flavone adducts. Their structures with absolute configurations were elucidated by detailed spectroscopic analyses and chemical calculations. The antibacterial and anti‐inflammatory activities of (+)‐ and (−)‐ 1 and 2 were evaluated.
