Tan, Pei Jean and Shaari, Khozirah and Paetz, Christian and Ismail, Intan Safinar and Abas, Faridah and Lajis, Md. Nordin and Ahmad, Viqar Uddin (2009) Bidesmosidic oleanane saponins from Xerospermum noronhianum. Helvetica Chimica Acta, 92 (10). pp. 1973-1982. ISSN 0018-019X; ESSN: 1522-2675


Three new oleanane-type triterpenoid saponins, 3-O-(α-L-rhamnopyranosyl(12)-β-D-fucopyranosyl)-28-O-{[α-L-rhamnopyranosyl(12)] [β-D-fucopyranosyl(16)]-β-D-glucopyranosyl} oleanolic acid (1), 3-O-[α-L-rhamnopyranosyl(13)-β-D-fucopyranosyl]-28-O-[α-L-rhamnopyranosyl(14)-β-D-glucopyranosyl] oleanolic acid (2), and 3-O-{α-L-rhamnopyranosyl(12)-[3′,4′-diacetoxy-β-D-fucopyranosyl]}-28-O-[α-L-rhamnopyranosyl(12)-β-D-glucopyranosyl] oleanolic acid (3) have been isolated from the stems of Xerospermum noronhianum. The structures of the saponins were determined as a series of bidesmosidic oleanane saponins based on spectral evidence. The anticholinesterase activity of the saponins 1–3 was also evaluated.
