Abstract:
:An approach, using well characterized procedures, is presented that should be of general applicability for the structural elucidation of complex sugar moieties of natural products. The methods used are exemplified by the structure elucidation of a new gitogenin-based steroidal saponin that has a strong leishmanicidal activity similar to preparations used in clinical practice and has been isolated by bioactivity-guided fractionation of the ethanolic extract of Yucca filamentosa L. leaves. The saponin has been characterized as 3-O-((beta-D-glucopyranosyl-(1-->3)- beta-D-glucopyranosy-(1-->2))(alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->3))-beta-D-glucopyranosyl-(1-->4)-beta-D-galactopyranosyl)-25R,5alpha-spirostan-2alpha,3beta-diol.
