          Abstract

          Two new triterpene saponins, 3-O-beta-D-glucopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucuronopyranosyl-22-O-angeloyl-R1-barrigenol (1) and 3-O-beta-D-glucopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucuronopyranosyl-22-O-beta,beta-dimethylacryloyl-A1-barrigenol (2), were isolated from the roots of Eryngium campestre (Apiaceae). Their structures were established mainly by 2D NMR techniques and mass spectrometry.

          Coumarin Derivatives from Eryngium campestre1.

          Aegelinol benzoate, a new dihydroxanthyletin ester and the known coumarin esters agasyllin and grandivittin, as well as, aegelinol have been isolated from ERYNGIUM CAMPESTRE roots using column chromatography and subsequent semipreparative HPLC. The structures of the compounds have been elucidated by a combination of spectroscopic methods.
