The molecule is a trihydroxyflavanone that is (2S)-flavanone substituted by hydroxy groups at positions 5, 7 and 4', a prenyl group at position 6 and a (2S)-2-methyl-2-(4-methylpent-3-en-1-yl)tetrahydro-2H-pyran ring fused across positions 2' and 3'. Isolated from the leaves of Macaranga tanarius, it exhibits antineoplastic activity. It has a role as a metabolite and an antineoplastic agent. It is a trihydroxyflavanone and a member of 4'-hydroxyflavanones.
