title: Three novel triterpenoid saponins from Lysimachia capillipes and their cytotoxic activities.
abstract: Three new saponins, capilliposide A (1), capilliposide B (2) and capilliposide C (3) were isolated from an ethanol extract of Lysimachia capillipes. Their structures were determined by 1D and 2D NMR (1H-1H COSY, HMBC, HMQC, DEPT and TOCSY) techniques, MS, and hydrolysis. Capilliposide B showed significant cytotoxicity against human A-2780 cells.
