Many web sites written in Japanese provide very suspicious information that the fruits ofkiwifruit are rich in psoralen, a phototoxic furocoumarin. In order to deny the suspiciousinformation, the furocoumarin content in the fruit of ‘Hayward’ and ‘ZESY002’ kiwifruit wasdetermined using reversed-phase high performance liquid chromatography(HPLC).Furocoumarins(psoralen, 5-methoxypsoralen, 8-methoxypsoralen and angelicin)have not beendetected in the fruits of both cultivars. The content of each furocoumarin in the fruits wasestimated as less than 2.36 μg per 100 g flesh weight from the detection limit in the HPLCsystem. The results in the present study have obviously shown it is the false information thatthe fruits of kiwifruit are rich in psoralen.
