기름나물 뿌리의 Coumarin 성분

Coumarin Components in the Root of Peucedanum terebinthaceum

Five compounds$(I{\sim}V)$ were isolated from the roots of Peucedanum terebinthacem growing in Korea. Compounds I, IV and V are ${\beta}-sitosterol$, bergapten and umbelliferone, respectively. IR and NMR spectra of compounds II (mp. $190^{\circ}$) and III(mp. $111{\sim}120^{\circ}$), both white needle crystalls, indicate that compounds II is a furocoumarin and that compound III, yielding decursinol upon saponification, is a pyranocoumarin.
