  A total of thirteen steroidal saponins, including four new furostanol saponins, were isolated from the fresh stems of Dracaena concinna. The structures of new saponins were determined by detailed analysis of their 1H and 13C NMR spectra, hydrolysis, and by comparison of spectral data of known compounds. Two of the new furostanol saponins are unique in structure possessing a 4α-hydroxyl group on the furostanol skeleton.

  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 → 2)-O-[β-D-xylopyranosyl-(1 → 3)]-β-D-xylopyranose with the formation of an O-glycosidic linkage to C- 1 of the aglycone.
