概要
Seven oleanane-type triterpenoid saponins, tunicosaponins B-D (1-3), F-I (4-7), along with eight known triterpenoid saponins (8-15), were isolated from the roots of Psammosilene tunicoides. The structures of compounds 1-7 were determined by comprehensive spectroscopic analysis, including 1D and 2D NMR techniques, mass spectrometry and chemical methods. Triterpene glycosides have been considered as major active constituents of P. tunicoides. This work provides a more complete insight into the saponin constituents of P. tunicoides.
