A new pyrone derivative, malakavalactone (2), was isolated from the acetone extract of Alpinia malaccensis fruits, along with a known compound kavalactone (1). The structure of the new compound was determined based on NMR and mass spectral data. Compounds 1 and 2 showed weak antibacterial activities against eight pathogenic bacteria.
