Whole plants and fruits of Glehnia littoralis collected in five places in Japan were cultivated in an experimental field in Niigata. The fruits harvested were assayed for their coumarins. The furanocoumarin composition of fruits differed considerably from those of roots and rhizomes: in fruit, imperatorin and phellopterin were major coumarins, xanthotoxin, bergapten, isoimperatorin and 8-geranyloxypsoralen were minor ones, and psoralen and bergamottin were undetectable in any sample analyzed. The total coumarin content (0.8-1.7%) of the fruit was higher than that (0.01-0.15 %) of the underground parts. About 60 % of the coumarins in the fruit were in the seed. There was a significant difference in the mericarp size among the plants collected in different places but, in contrast to the case of the underground organs, little geographical variability was observed in the furanocoumarin composition and content of the fruit.
