NEW COMPONENTS OF ROOT TAR OF THE BILACUNARIA MICROCARPA (M. BIEB.) PIMENOV & V.N. TIKHOM.
Abstract
The biologically active substances isolated from root resin of the Bilacunaria microcarpum M.Pimen. et V.Tichomirov. was investigated. Besides osthol, bergapten, izoimperatorin, oxypeucedanin, peucedanin hydrate, have been isolated two new individual crystalline compounds C15H14O4, m.p. 108–109 °C (I) and C16H16O6, m.p. 127–129 °C (II). On the basis of spectral the data (IR, 1H NMR, 13C, 13C Dept 90, Dept 235) it was ascertained that they have a structure identical to the structure of peucedanin (I) and prangenin hydrate (II), respectively.
