Steroidal glycoalkaloids in tubers and leaves of Solanum species used in potato breeding

The compositions of glycosidic-bound steroidal alkaloids (SA) of Solanum species used in potato breeding were assessed by capillary gas chromatography using simultaneous nitrogen-specific (NPD) and flame-ionisation detection (FID). High concentrations of solanidine glycosides and other steroidal gly...

Zusammenfassung:The compositions of glycosidic-bound steroidal alkaloids (SA) of Solanum species used in potato breeding were assessed by capillary gas chromatography using simultaneous nitrogen-specific (NPD) and flame-ionisation detection (FID). High concentrations of solanidine glycosides and other steroidal glycoalkaloids, amongst which the teratogenic SA solasodine, were found in tubers and leaves of wild species. In addition unidentified compounds were found, which were most probably SA as was shown by their NPD/FID response ratios. The total glycoalkaloid contents varied from 123 to 7348 mg/kg fresh weight.
