A diosgenyl saponin has been extracted from the rhizomes of Paris Polyphylla Smith,and determined to be diosgenin 3-O-α-L-rhamnopyranosyl-(1→2)-[α-L-arabinofuranosyl-(1→4)]-β-D-glucopyranoside. The NMR chemical shifts of the compound have been assigned using 1D and 2D NMR spectroscopy,including 1H-1H COSY,HSQC and HMBC. Selective 1D TOCSY experiments have been performed to assign the crowded spectral region from glycosidic protons.
