STEROIDAL SAPONINS FROM THE BULBS OF TRITELEIA LACTEA AND THEIR INHIBITORY ACTIVITY ON CYCLIC AMP PHOSPHODIESTERASE

Article abstract of DOI:10.1016/0031-9422(94)00790-Z

The chemical compounds in the bulbs of Triteleia lactea have been analysed as a part of our systematic study of plants of the subfamily Allioideae in Liliaceae.Thirteen steroidal saponins, seven of which appeared to be new compounds, were isolated.The structures of the new saponins were elucidated on the basis of the spectroscopic analysis, including two-dimensional NMR techniques, and hydrolysis.Inhibitory activity of the isolated saponins on cyclic AMP phosphodiesterase was evaluated to identify new compounds with medicinal potential. - Key words: triteleia lactea; Allioideae; Liliaceae; bulbs; steroidal saponins; spirostanol saponins; cyclic AMP phosphodiesterase inhibition.
