A new tdterpenoid glycoside, 3-β-O-β-D-glucopyranosyl presenegenin 28-O-α-L-arabipyranosyl(1 → 3)-6-β- xylopyranosyl(1 → 4)-[β-D-apiofuranosyl(1 → 3)]-Ct-L-rhamnopyranosyl(1 → 2)-[α-L-rhamnopyranosyl(1 → 3)]-β-D-fucopyranosyl ester (1) was isolated from the Polygala tenuifolia Willd., together with two known saponins, including polygalasaponinXXIV (2) and polygalasaponinXXVIII (3). The structure of new compound was elucidated by spectroscopic methods.

Two new steroidal glucosides, 26-O-β-D-glucopyranosyl (25S)-furost-5-ene-1β,3β,22α,26-tetraol l-O-β-D-xylopyranosyl- (1 → 3)-[α-h-rhamnopyranosyl-(1 → 2)]-[β-D-fueopyranoside and (25R) spirost-5-ene-3β,14α-diol-3-β-O-β-L-rhanmopyranosyl- (1 → 2)-[β-D-xylopyranosyl(1 → 4)]-[-β-D-glucopyranoside, were isolated from the Ophiopogon japonicus (L.f.) Ker-Gaw. Their structures were elucidated by spectroscopic methods.
