Investigation Of The Coumarin Derivatives Of Aerial Parts Of Peucedanum ruthenicum

Three coumarin derivatives: I) CısHiO4, mp. 108-109°C; II) CısHịO4, m.p. 109-110°C; III) CioHO3, m.p. 17-118°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- (H, *C, "C Dept 135, Dept 90) spectral data they have been identi- fied as isoimperatorin, peucedanin and ostrutin respectively.
