Four triterpene saponins, 3-O-beta-D-glucopyranosylpresenegenin 28-O-beta-D-apiofuranosyl-(1 -> 3)-beta-D-xylopyranosyl-(1 -> 4)-[beta-D-apiofuranosyl-(1 -> 3)]-alpha-L-rhamnopyranosyl-(1 -> 2)-{4-O-[(E)-3,4,5-trimethoxycinnamoyl]}-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosylpresenegenin 28-O-beta-D-apiofuranosyl-(1 -> 3)-beta-D-xylopyranosyl-(1 -> 4)-[beta-D-apiofuranosyl-(1 -> 3)]-alpha-L-rhamnopyranosyl-(1 -> 2)-[(6-O-acetyl)-beta-D-glucopyranosyl-(1 -> 3)]-{4-O-[(E)-3,4,5-trimethoxycinnamoyl]}-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosylpresenegenin 28-O-beta-D-apiofuranosyl-(1 -> 3)-beta-D-xylopyranosyl-(1 -> 4)-[beta-D-apiofuranosyl-(1 -> 3)]-alpha-L-rhamnopyranosyl-(1 -> 2)-[beta-D-galactopyranosyl-(1 -> 3)]-{4-O-[(E)-3,4,5-trimethoxycinnamoyl]}-beta-D-fucopyranosyl ester, and 3-O-beta-D-glucopyranosylpresenegenin 28-O-beta-D-apiofuranosyl-(1 -> 3)-[alpha-L-arabinopyranosyl-(1 -> 4)]-beta-D-xylopyranosyl-(1 -> 4)-[beta-D-apiofuranosyl-(1 -> 3)]-alpha-L-rhamnopyranosyl-(1 -> 2)-{4-O-[(E)-3,4,5-trimethoxycinnamoyl]}-beta-D-fucopyranosyl ester, were isolated from the roots of Securidaca longepedunculata, together with three known compounds. Their structures were established mainly by 2D NMR techniques and mass spectrometry.
