A novel isoflavone wrightiadione, was isolated from Wrightia tomentosa. Determination of the carbon framework was based on the interpretation of NMR and mass spectral data, and the structure was confirmed by X-ray analysis. This compound displays cytotoxic activity against the murine P388 lymphocytic leukemia cell line (ED50, 1.1 mug ml-1).
