A new coumestan, 1,3,9-trihydroxy-8-methoxycoumestan, named flemicoumestan A 1 together with nine isoflavone-related compounds were isolated from the ethyl acetate extract of the roots of Flemingia philippinensis. Their structures were elucidated and confirmed by spectroscopic methods and literature data. Compounds 3 and 4 showed strong lymphocyte proliferation inhibitory activity with an IC(50) value of 1.04-2.76 μM, and the low cytotoxicity with the CC(50) value of 71.01 and 56.36 μM, respectively.
