Triterpene saponins from the roots of Parkia bicolor A. Chev

Abstract : Five undescribed triterpene-type saponins, parkibicolorosides A–E, a cassane-type diterpene, and a known trimethoxy benzene glucoside were isolated from the roots of Parkia bicolor A. Chev. Their structures were elucidated by different spectroscopic methods including 1D- and 2D-NMR experiments as well as HR-ESI-MS analysis. Their cytotoxic activity against the chronic myeloid leukemia (K562) cell line was evaluated. The monosaccharides saponins exhibited a moderate antiproliferative activity with IC50 ranging from 48.49 ± 0.16 to 81.66 ± 0.17 μM.
