Caspicaosides E-K, triterpenoid saponins and cytotoxic acylated saponins from fruits of Gleditsia caspica Desf.

Seven triterpenoid saponins named caspicaosides E-K were isolated from the fruits of Gleditsia caspica Desf. Their structures were determined by 1D and 2D NMR spectroscopy as well as HR-MS and acid hydrolysis.
