  From the essential oil of fruits of Peucedanum tauricum Bieb., two guaiane type sesquiterpene hydrocarbons guaia-1(10),11-diene (1) and guaia-9,11-diene (2) were identified. The structures of 1 and 2 were assigned by 1D and 2D NMR analysis. The relative configurations of the compounds were established by 2D-NOESY experiments while the absolute configurations were deduced through chemical correlations with (+)-gamma-gurjunene (9) and capillary GC analysis using modified cyclodextrins as the stationary phases. From the dichloromethane extract of the less volatile fraction of the fruits, coumarins, viz. peucedanin (3), oxypeucedanin hydrate (4) and officinalin isobutyrate (5) were isolated. Compound 5 was confirmed to be 6-carbomethoxy-7-isobutyroxycoumarin by its ID and 2D NMR data as well as by conversion into officinalin (7) by alkaline hydrolysis. Peuruthenicin, a positional isomer of officinalin, is assigned structure 8 on spectral basis. Bergapten (6) was identified by its mass spectrum. This is the first report on the isolation of compounds 4 and 5 from P. tauricum. (c) 2005 Elsevier Ltd. All rights reserved.

  The structure of 2-bromooreoselon, which was prepared by bromination of peucedanin or oreoselon with molecular bromine, was established. The compositions and structures of the reaction products of this bromide with amines, such as pyridine, triethylamine, and morpholine, as well as with sodium acetate and potassium hydroxide were studied. The reaction of peucedanin with m-chloroperoxybenzoic acid affords peuruthenicin isobutyrate.
