Three new ester glycosides with cytotoxic activity from the seeds of .

Three new ester glycosides, named as Caesateroside A (), Caesateroside B () and Caesateroside C () were obtained from the seeds of . The new structures of compounds were elucidated by analyzing their 1 D NMR, 2 D NMR and HR-ESI-MS spectra. Compounds showed weak-moderate cytotoxicity against Hela and HepG-2 human cancer cell lines.
