Definition:A tetrahydroxyflavanone that is (2S)-flavanone substituted by hydroxy group at positions 5, 7, 3' and 4' and a geranyl group at position 2'. Isolated from Macaranga tanarius and propolis collected in Okinawa, it exhibits radical scavenging activity.
Synonyms:exact_synonym: (2S)-2-{2-[(2E)-3,7-dimethylocta-2,6-dien-1-yl]-3,4-dihydroxyphenyl}-5,7-dihydroxy-2,3-dihydro-4H-chromen-4-one
