Four new triterpenoid saponins, ardisimamilloside C (1), 3-O-{α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranosyl}-3β, 16α, 28,30-tetrahydroxy-olean 12-en, ardisimamilloside D (2), 3-Or-{α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranosyl}-3β, 15α, 28,30-tetrahydroxy-olean-12-en, ardisimamilloside E (3), 3-O-{α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranosyl}-13β, 28-epoxy-3β, 16α, 29-oleananetriol, and ardisimamilloside F (4), 3-O-{α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranosyl}-3β, 16α-dihydroxy-13β, 28-epoxy-oleanan-30-oic acid were isolated from the roots of Ardisia mamillata HANCE. Structure assignments were established on the basis of highresolution (HR)-FAB-MS, ^1H-, ^<13>C-, and two-dimensional (2D)-NMR spectra, and on hte chemical evidence.
