Four new allose-containing triterpenoid saponosides, scabriosides A, B, C and D were isolated from the roots of Scabiosa rotata. Their structures were established as 3-O-beta-D-xylopyranosyl-28-O-[beta-D-allopyranosyl(1 --> 6)-beta-D-glucopyranosyl]-pomolic acid, 3-O-[alpha-L-rhamnopyranosyl(1 --> 2)-beta-D-xylopyranosyl]-28-O-[beta-D-allopyranosyl(1 --> 6)-beta-D-glucopyranosyl]-pomolic acid, 3-O-[a-L-rhamnopyranosyl (1 --> 2)-alpha-L-arabinopyranosyl]-28-O-[beta-D-allopyranosyl(1 --> 6)-beta-D-glucopyranosyl]-pomolic acid, and 3-O-[beta-D-grucopyranosyl(1 --> 3)-alpha-L-rhamnopyranosyl(l --> 2)-beta-D-xylopyranosyl]-28-O-[beta-D-allopyranosyl(1 --> 6)beta-D-glucopyranosyl]-pomolic acid, respectively, by the help of spectral evidence (IR, 1D- and 2D-NMR, FABMS).
