    Plant Coumarins. 3. (+)-PTeryxin from Peucedanum terebinthaceum.[Reference: WebLink]
    The potentially medically valuable pyranocoumarin (+)-Pteryxin was isolated for the first time from Peucedanum terebinthaceum Fischer et Turcz. The structure of (+)-Pteryxin was rigorously proved using mass spectrometry, NMR, IR, and UV spectroscopy and comparison of the spectral characteristics of this compound and its basic hydrolysis products (+)-cis- and (−)-trans-khellactone and angelic and acetic acids.
