The molecule is a dihydroxyflavanone that is (2S)-flavanone substituted by hydroxy groups at positions 5 and 7, prenyl groups at positions 8 and 3' and a 6,6-dimethyl-3,6-dihydro-2H-pyran ring fused across positions 4' and 5'. Isolated from the stem barks of Maackia amurensis, it exhibits cytotoxicity against human cancer cell lines. It has a role as a metabolite and an antineoplastic agent.
(2S)-2-[2,2-dimethyl-8-(3-methylbut-2-enyl)chromen-6-yl]-5,7-dihydroxy-8-(3-methylbut-2-enyl)-2,3-dihydrochromen-4-one
