A new pregnane hexaglycoside, named amurensioside L (1), was isolated from the whole plant of Adonis multiflora. Amurensioside L (1) emerged to be new pregnane hexaglycoside which we fully spectroscopically characterized. The chemical structure of compound 1 was established as $14{\beta}$,20R-epoxy-$3{\beta}$-hydroxypregna-4,6-dien-18-oic acid-20-lactone 3-O-${\beta}$-$\small{D}$-glucopyranosyl-($1{\rightarrow}4$)-O-${\beta}$-$\small{D}$-diginopyranosyl-($1{\rightarrow}4$)-O-${\beta}$-$\small{D}$-cymaropyranosyl-($1{\rightarrow}4$)-O-${\beta}$-$\small{D}$-cymaropyranosyl-($1{\rightarrow}4$)-O-${\beta}$-$\small{D}$-oleandropyranosyl-($1{\rightarrow}4$)-O-${\beta}$-$\small{D}$-oleandropyranoside on the basis of spectroscopic analyses including nuclear magnetic resonance spectrometry, high-resolution fast atom bombardment mass spectrometry, and infrared spectroscopy.
