Two new alkaloids from the sepals of Solanum melongena L

Two new alkaloids named Melongenamides H-I (1-2), together with twenty-one known compounds (3-23), were isolated from the 70% ethanol extract of the sepals of Solanum melongena L. The structures of all isolated compounds were determined by 1D and 2D NMR spectra and by comparing their spectroscopic and physical data with values from the published literatures. All the isolated compounds were evaluated the cytotoxicity against three human canner...
