Three coumarin derivatives: I) C16H14O4, m.p. 108-109°C; II) C15H14O4, m.p. 109-110°C; III) C19H22O3, m.p.
117-118°C have been isolated using chromatography of obtained compounds after extraction from the aerial
parts of Peucedanum ruthenicum M.B., collected from Yasamal passage of Shamkir region of the Azerbaijan
Republic. On the base of IR- and NMR- (1Н, 13С, 13С Dept 135, Dept 90) spectral data they have been identified
as isoimperatorin, peucedanin and ostrutin respectively.
