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