? 2022 Phytochemical Society of EuropeTwo new oleanane-type triterpene glycosides, 3?O?β?D?glucopyranosyl?28?O?[β?D?glucopyranosyl?(1→2)?β?D?xylopyranosyl?(1→6)?β?D?glucopyranosyl]medicagenic acid (1) and 3?O?β?D?glucopyranosyl?28?O?[β?D?glucopyranosyl?(1→6)?β?D?glucopyranosyl?(1→2)? β?D?xylopyranosyl]oleanolic acid (2), named capitatosides A and B respectively, were isolated from the butanol extract of Paronychia capitata (L.) Lam., along with seven known compounds. The structures of the isolated compounds were established by spectroscopic methods, mainly HRMS, 1D and 2D NMR (1H, 13C, COSY, HSQC, HMBC and NOESY) techniques, whereas those of the known compounds were identified by spectral comparison with reported literature data.
