Three new sulphate ester salts derived from known coumarin alcohols - one of them tertiary - have been obtained from roots of Seseli libanotis subsp. eu-libanotis.Their structures were established as (2'S)-rutaretin-1''-sulphate, (3'R)-lomatin-3'-sulphate and (3'R,4'R)-khellactone-3'-sulphate.They were together with their parent alcohols characterized by 13C NMR spectroscopy.It is the first report on coumarin sulphates in plants.Key Word Index - Seseli libanotis subsp. eu-libanotis; Umbelliferae; dihydrofurocoumarins; dihydropyranocoumarins; coumarin sulphates; sulphate ester salts; FDMS; 13C NMR.
