A novel prenylated flavanone was isolated from ethyl acetate extracts of the hard-wood cutting root of Kinuyutaka, a cultivar of Morus alba. The structure, 7, 2', 4', 6'-tetrahydoroxy-6-geranylflavanone, was revealed by spectral analyses. This prenylated flavanone exhibited cytotoxic activity against rat hepatoma (dRLh84) cells with an IC50 of 52.8μg/ml.
