摘要：

Three new furostanol glycosides, named ciliatasides A, B, and C (1-3, resp.), have been isolated from the roots of Digitalis ciliata, along with two known furostanol glycosides. The structures of the new compounds were identified as (2 alpha, 3 beta, 5 alpha, 14 beta, 25R)-26-(beta-D-glucopyranosyloxy)-2-hydroxyfurost-20(22)-en-3-yl beta-D-glucopyranosyl-(1 -> 2)-[beta-D-glucopyranosyl-(1 -> 3)]-beta-D-galactopyranoside (1), (2 alpha, 3 beta, 5 alpha, 14 beta, 22R)-26-(beta-D-glucopyranosyloxy)-2-hydroxy-22-methoxyfurost-25(27)-en-3-yl beta-D-galactopyranosyl-(1 -> 2)-[beta-D-xylopyranosyl-(1 -> 3)]-beta-D-glucopyranosyl-(1 -> 4)-beta-D-galactopyranoside (2), and (2 alpha, 3 beta, 5 alpha, 14 beta, 22R, 25R)-26-(beta-D-glucopyranosyloxy)-2,22-dihydroxyfurostan-3-yl beta-D-glucopyranosyl-(1 -> 2)-[beta-D-glucopyranosyl-(1 -> 3)]-beta-D-galactopyranoside (3).
