Two novel cholestane-type steroidal saponins, melongoside R-S (1-2) and three novel furostanol-type steroidal saponins, melongoside T-V (3-5), together with three known steroidal saponins (6-8) were isolated from the seeds of Solanum melongna L. The structures of these compounds were elucidated by extensive spectroscopic analysis such as HR-ESI-MS, ESI-MS and NMR.
