Olefinic and acetylenic butenolides from Peucedanum alsaticum

The lipophilic root extract of Peucedanum alsaticum afforded four highly unstable butenolides which could be separated by HPLC. Whereas the stereochemistry of three olefinic derivatives, previously isolated only as their methyl ethers, were now established by 1H NMR, the structure of a new acetyleni...

Summary:The lipophilic root extract of Peucedanum alsaticum afforded four highly unstable butenolides which could be separated by HPLC. Whereas the stereochemistry of three olefinic derivatives, previously isolated only as their methyl ethers, were now established by 1H NMR, the structure of a new acetylenic lactone was additionally confirmed by 13C NMR. The compounds are probably formed by condensation of unsaturated C 18-acids with pyruvate.
