A new steroidal saponin, chloragin (1), was isolated and characterised from the aerial part of Chlorophytum nimonii. The structure of chloragin (1) was established as tigogenin-3-O-alpha-L-rhamnopyranosyl-(1 --> 4)-beta-D-glucopyranosyl-(1 --> 3)-beta-D-xylopyranosyl-(1 --> 4)-beta-D-glucopyranosyl-(1 --> 4)-beta-D-xyloopyranoside on the basis of detailed chemical and spectral evidence. The saponin showed potent antihyperglycaemic and antidyslipidaemic activities in albino rats.
