Three new spirostanol saponins and two new furostanol saponins were isolated from the fresh leaves of Cordyline stricta. Their structures were elucidated on the basis of spectroscopic analysis, including various 2D-NMR techniques, hydrolysis, and by comparison of spectral data of known compounds. Two of the isolated saponins contained a new branched triglycoside moiety assigned as O-α-l-rhamnopyranosyl-(1...
A phytochemical study on the leaves of Cordyline stricta yielded four new spirostanol saponins, three new furostanol saponins and a new pregnane glucoside. The structures were determined by detailed analysis of their 1 H and 13 C NMR spectra, acid-catalysed hydrolysis and by comparison with spectral data of known compounds. Each of the isolated steroidal compounds contained...
