1H- and 13C-nmr assignments and structural determination of a novel glycoalkaloid from Solanum platanifolium.
Four steroidal glycoalkaloids, solasonine [2], solamargine [3], khasianine [4], and ravifoline [5], with solasodine [1] as the aglycone moiety, have been isolated from Solanum platanifolium. The present study involved the characterization of the novel compound 5 by one- and two-dimensional nmr techniques and has also led to the unambiguous and total 13C- and 1H-nmr assignments of all of these steroidal glycoalkaloids and the direct elucidation of their glycosidic linkages.
