Hydrocotylosides I-VII, new oleanane saponins from hydrocotylesibthorpioides.
Seven new oleanane-type triterpenoid saponins, hydrocotylosides I-VII (1-7), and one known saponin, udosaponin B (8), were isolated from the methanol extract of the whole plants of Hydrocotyle sibthorpioides.The structures of the new compounds were elucidated on the basis of chemical and spectroscopic evidence.
