A new triterpenoid saponin, protoprimuloside B (2), has been isolated from the roots of Primula elatior subsp. meyeri and its structure deduced as 3 beta -O-{[alpha -L-rhamnopyranosyl-(1-2)-beta -galactopyranosyl-(1-3)]-[beta -D-glucopyranosyl-(1-2)]-beta -D-glucopyranosyl}-protoprimuloside B by means of spectral data, especially NMR (400 MHz), including H-1, C-13, DEPT, COSY, HMBC, HMQC, NOESY techniques and (+)FAB-MS spectrum.
