title: New chalcones bearing a long-chain alkylphenol from the rhizomes of Alpinia galanga.
abstract: Three novel chalcones bearing a long-chain alkylphenol, galanganones A-C (1-3), were isolated from the rhizomes of Alpinia galanga. Their structures were elucidated by extensive spectroscopic analysis including 2D NMR experiments. Compounds 1-3 represent the first examples of long-chain alkylphenol-coupled chalcone.
