Abstract
Chromatography of extracts from sections of the root of P. magna showed that coumarinic acid is incorporated into furocoumarins, whereas coumarin is utilized to only a very small extent. Accordingly, it is to be assumed that furocoumarins are formed from cinnamic acid, although not by way of coumarin. Umbelliferon proved to be the best precursor. From this it is concluded that a hydroxyl group is introduced into cinnamic acid in the para-position before ortho-hydroxylation occurs. The origin of the 2 additional C-atoms of the furan ring is still not clear. They might come from C-atoms 4 and 5 of mevalonic acid. An experiment with mevalonic acid [4-C14] was inconclusive.This publication has 1 reference indexed in Scilit:
