The coumarinic compounds of fig leaves (Ficus carica) here examined closely. The furocoumarins psoralen, bergapten and the coumarins umbelliferone, 4',5'-dihydropsoralen and marmesin are present. These substances were determined in a "coumarinic extract" by high pressure liquid chromatography
Bioassay-guided fractionation of the active AcOEt-soluble layer led to the isolation of two new pyranocoumarins, 3-hydroxyxanthyletin (1) and 3-methoxyxanthyletin (2), along with 22 known compounds including four simple coumarins, i.e., xanthyletin (3), umbelliferone (4), scopoletin (5), and
