TL;DR: Three triterpenoid saponins including two new ones were isolated and identified from the aerial parts of Fagonia cretica by means of NMR studies and spectral analyses.
Abstract: Three triterpenoid saponins including two new ones were isolated and identified from the aerial parts of Fagonia cretica. The new saponins were characterized as 3-O-[beta-D-xylopyranosyl(1-->2)alpha-L-arabinopyranosyl]27-hydroxyoleanolic acid 28-O-[beta-D-glucopyranosyl(1-->6)beta-D-glucopyranosyl]ester and 3 beta-O-[beta-D-xylopyranosyl(1-->2)alpha-L-arabinopyranosyl] olean-12-en-27-al-28-oic acid 28-O-[beta-D-glucopyranosyl(1-->6)beta-D-glycopyranosyl] ester. The structures were determined by spectral analyses. The NMR assignments were made by means of HOHAHA, 1H-1H COSY, HMQC, HMBC spectra and NOE studies.
