Abstract: A ne steroidal saponin,named chloromaloside E,was isolated from the fresh rhizomes of Chlorophytum malayense,together with three known saponins,chloromaloside A-C. Using the spectral and chemical methods,the structure of chloromaloside E was elucidated as 26-O-β-D-glucopyranosyl-22 hydroxy-25(S)-5α-furostan-12 -oxo-3β,26-diol 3-O-β-D-xylopyranosyl(1→3)[α-L-arabinopyanosyl(1→ 2)]-β-D-glucopyranosyl(1→4)-[α-L-rhmnopyranosyl(1→ 2)]-β-D-galactopyranoside.
