Abstract
Two steroidal saponins were isolated from MeOH extract of the rhizomes of Asparagus oligoclonos. Using the spectroscopic techniques of ¹H, ^(13)C NMR and 2D NMR, they were identified as 3-O-[β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl]-(25S) -spirostan-3β-ol and 3-O-[β-D-glucopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→4)]-β-D-glucopyranosyl]-(25S)-spirostan-3β-ol, respectively. They were first isolated from A. oligoclonos. The in vitro antibacterial activities as well as antibacterial spectrums against 20 bacteria strains were investigated with MIC test. Both saponins inhibited the growth of 10 bacteria strains at the concentration of 100㎍/㎖.
