„The thick root has a strong odour of sulphur - hence one of the other popular names of the plant, Sulphurwort, and when wounded in the spring, yields a considerable quantity of a yellowish-green juice, which dries into a gummy resin and retains the strong scent of the root.“

„This harvesting technique,and the product so obtained, very much recall those of two other medicinal umbellifers: Ferula assa-foetida and Dorema ammoniacum.“ https://en.wikipedia.org/wiki/Peucedanum_officinale

The dried roots (Radix Peucedani, Radix Foeniculi porcini) own a disgusting smell and salty bitter taste. They contain essential oil (0.2%, bad smell), peucedanin (2-2.5%), and oxypeucedanin (0.3-0.5%). Used formerly in folk medicine as diuretic and to treat malaria, catarrh and gonorrhea.

„The volatile constituents of Peucedanum officinale L were isolated by hydrodistillation and the essential oil were analyzed by GC and GC/MS. Thirty-eight compounds representing 98.7% of the oil in leaf were identifed, of which fenchone (27.7%), (E)-β-ocimene (18.7%) and β-pinene (8.1%) were major. Twenty-two compounds representing 99.7% of the oil in the seeds were identifed, of which fenchone (32%), (E)-β-ocimene (17.8%), and (Z)-β-ocimene (9.4%) were major.“

The essential oil of the rhizome of P.officinale contained limonene (28.2%) and α-pinene (28.1%) as main constituents. α-Pinene (24.8%), β-pinene (17.6%), limonene (11.3%) and myrcene (9.5%) were the major compounds found in the volatile oil of the leaves.

Main component of the essential oil from flowering plants of P.officinale collected in Greece was bornyl acetate (81.1%).
