Four new prenylated xanthones, cudracuspixanthones A–D (14), two new prenylated benzophenones, cudracuspiphenones A (5) and B (6), and 11 known xanthones (717) were isolated from the roots of Cudrania tricuspidata. The absolute configurations of compounds 24 were deduced by the comparison of the calculated optical rotation values with the measured data. Compounds 1, 5, and 6 showed moderate antiproliferative activity on HSC-T6 cells with IC50 values of 9.7, 3.3, and 7.1 μM, respectively. Compounds 24, 10, and 1416 had weaker activity. Flow cytometric analysis suggested that compounds 1 and 5 inhibited HSC-T6 cell proliferation in part by inducing apoptosis.
