Summary
The seeds of the resin-bearing plantPrangos pabularia Lindl. contain 17–19% of a complex mixture of substances extractable with petroleum ether, including 6.54% of fatty oil. The following saturated acids have been found in the oil: behenic, arachidic, stearic, and palmitic; and the following unsaturated acids: linoleic, oleic, and petroselinic, which is characteristic for the family Umbelliferae.
The non-glyceride complex of the oil has been shown to contain β-carotene and another pigment of undetermined structure, the hydrocarbon n-nonacosane, and, two coumarin derivatives, osthol and another with mp 109°, the structure of the latter not having been established.
