Structures of two new fibrinolytic saponins from the seed of Luffa cylindrica Roem.
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-beta-D-galactopyranosyl-(1----2)-beta-D-glucuronopyranosyl-28- O-beta-D-xylopyranosyl-(1----4)-[beta-D-glucopyranosyl-(1----3)]-alpha-L -rhamnopyranosyl-(1----2)-alpha-arabinopyranosyl quillaic acid. Lucyoside P was characterized as a gypsogenin glycoside with the same sugar moiety as lucyoside N.
