The Authors have studied the capacity to photoreact with native DNA and r-RNA using six coumarins and four 4',5'-dihydro-furo-coumarins. Six of these substances have shown a definite photoreactivity both with DNA and r-RNA, even if in a very much lower extent in respect to that of skin-photosensitizing furocoumarins. The low capacity to photoreact with nucleic acids of these substances is discu...

In a general research program on furocoumarins and coumarins from this plant we recently de­ scribed 4 the identification of the five furocouma­ rins, bergapten, imperatorin, isopimpinellin, prangenin and prangenin hydrate in the seeds obtained from ripe fruits of plants cultivated in the area of Padua.
