Two new fibrinolytic saponins, lucyosides N and P, were isolated from the seeds of Luffa cylindrica ROEM. (Cucurbitaceae). On the basis of chemical and spectral evidence, lucyoside N was characterized as 3-O-β-D-galactopyranosyl-(1→2)-β-glucuronopyranosyl-28-O-β-D-xylopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→3)]-α-L-rhamnopyranosyl-(1→2)-α-arabinopyranosyl quillaic acid. Lucyoside P was characterized as a gypsogenin glycoside with the same sugar moiety as lucyoside N.
