A novel glycosidic steroidal alkaloid from Solanum aculeastrum
Abstract
The root bark of Solanum aculeastrum Dunal yielded a new steroidal alkaloid
glycoside characterised as (25R)-3b-{O-a-L-rhamnopyranosyl-(1®2)-[O-b-D-glucopyranosyl-(1®4)-
O-a-L-rhamnopyranosyl-(1®4)]-b-D-glucopyranosyl}-22a-N-spirosol-5-ene. The structure was
established by spectroscopic analysis and comparison with published data of similar compounds
reported in literature.
