Chemical constituents of Selinum cryptotaenium.

ABSTRACT

A new pyranocoumarin, named secryptotaenin A, determined as 3'(S)-angeloyloxy-3',4'-dihydroseselin, was isolated from the roots of Selinum cryptotaenium, along with thirteen known compounds, umbelliferone, osthol, coumurrayin, (+)-heraclenol, longshengensin A, anomalin, ferulic acid, galactitol, stearic acid, melissic acid, lignoceric acid, beta-sitosterol and daucosterol. Their structures were determined on the basis of spectroscopic methods.
