A new triterpene glycoside from Centella erecta

A new (2α,3β)-23-sulphonyl-2,3-dihydroxyurs-12-en-28-oic acid O-α-l-rhamnopyranosyl-(1→4)-O-β-d-glucopyranosyl-(1→6)-O-β-d-glucopyranosyl ester (1) together with eighteen known compounds were isolated from Centella erecta (L.f.) Fern. Their structures were elucidated mainly by NMR and HRESIMS, as well as on comparison with the reported data.
