Three new spirotanol pentaglycosides embracing β-d-apiofuranose were isolated from the
fresh underground parts of Chlorophytum comosum together with four known saponins. The
structures of new compounds were determined by spectroscopic data, including two-
dimensional NMR, and partial acid-catalysed hydrolysis to be (25R)-5α-spirostane-2α, 3β-
diol 3-O-{O-β-d-glucopyranosyl-(1→ 2)-O-[O-β-d-apiofuranosyl-(1→ 4)-β-d-glucopyranosyl-
(1→ 3)]-O-β-d-glucopyranosyl-(1→ 4)-β-d-glactopyranoside}(25R)-3β-hydroxy-5α-spirostan …
