title: C-27 and C-3 glucosylation of diosgenin by cell suspension cultures of Costus speciosus.
abstract: 3-O-[beta-D-glucopyranosyl-(1"--> 2')-beta-D-glucopyranosyl], 27-O-beta-D-glucopyranosyl-(25R)-spirost-5-ene-3beta,27-diol was isolated from cell suspension cultures of Costus speciosus, following incubation with diosgenin, and its structure was elucidated using a combination of one- and two-dimensional 1H and 13C NMR spectral data, and positive and negative ion ESMS spectral data.
