Four new steroidal saponins, chloromalosides A-D, were isolated from the rhizomes of Chlorophytum malayense.On the basis of detailed chemical and spectroscopic evidence, the structures of chloromalosides A-D were elucidated to be neohecogenin 3-O-β-D-glucopyranosyl(1->2)-<β-D-xylopyranosyl(1->3)>-β-D-glucopyranosyl(1->4)-β-D-galactopyranoside, 26-β-D-glucopyranosyl-22-hydroxy-25(S)-5α-furostane-3β,26-diol-3-O-β-D-glucopyranosyl(1->2)-<β-D-xylopyranosyl(1->3)>-β-D-glucopyranosyl(1->4)-β-D-galactopyranoside, neohecogenin 3-O-β-D-xylopyranosyl(1->3)-<α-L-arabinopyranosyl(1->2)>-β-D-glucopyranosyl(1->4)-<α-L-rhamnopyranosyl(1->2)>-β-D-galactopyranoside and neotigogenin 3-O-β-D-xylopyranosyl(1->3)-<α-L-arabinopyranosyl(1->2)>-β-D-glucopyranosyl(1->4)-<α-L-rhamnopyranosyl(1->2)>-β-D-galactopyranoside, respectively.
