Objective: To investigate the steroidal glycoside constituents of Solanum cumingii.
Methods: The compounds were isolated by silica gel, Sephadex LH-20, RP-C18 column and Pre-HPLC chromatography. Their structures were identified by ESI-MS and NMR.
Results: Six known compounds including torvoside K (1), torvoside J (2), torvoside L (3), khasianine (4), aculeatiside A (5) and solamargine (6) were isolated from Solanum cumingii.
Conclusion: All compounds are isolated from Solanum cumingii for the first time.
