title: New triterpenoid saponins from the flowers of Pueraria thomsonii.
abstract: Two new oleanane-type triterpenoid saponins, kakkasaponin II (1) and kakkasaponin III (2), were isolated from the methanol extract of the flowers of Pueraria thomsonii (Leguminosae), together with seven known oleanane-type triterpenoid saponins, phaseoside IV (3), sophoradiol monoglucuronide (4), kakkasaponin I (5), kaikasaponin III (6), soyasaponin I (7), soyasaponin III (8), and soyasaponin IV (9). The structures of 1 and 2 were elucidated by spectroscopic methods including IR, ESI-TOF-MS, and 1D and 2D NMR experiments.
