Opopanax chironium is a rich source of furano- and dihydrofuranocoumarins, whose accumulation in all plant parts and especially the roots is presumably responsible for the poisonous properties of the species. The presence of two distinct chemotypes was evidenced, with the one from Sicily affording
The ethereal extract of the roots of Opopanax chironium yielded peucelinenoxide acetate (1), a new natural product with an irregular diterpene skeleton, besides the known coumarins gaudichaudin, columbianadin, peucedanin and officinalin isobutyrate.
Phytochemical investigation of chloroform extract of the aerial parts of Opopanax hispidus afforded a new dihydrofuranocoumarin, 3'-isobutyryl-3'-hydroxymarmesin (1a), together with six known coumarins, oreoselon, peucedanin, officinalin, smirniorin, 4'-acetyl-3'-isobutyryl-3'-hydroxymarmesin and
