The new glucosides tubeimoside II (I), III, IV isolated from the bulbs of B. paniculatum (Cucurbitaceae) were characterized by spectral analyses and chem. degrdns. Tubeimoside II and III are two novel macrocyclic saponins with a dicrotalic acid moiety bridging between the two sugar chains, and tubeimoside IV is 3-O-[-a-L-arabinopyranosyl (1 ?2)-b-D-glucopyranosyl]-3b, 7b, 18, 20, 26-pentahydroxy-(20S)-dammar-24-ene, the only tetracyclic triterpenoid saponin isolated from B. paniculatum.
