Five new pregnane tetraglycosides, amurensiosides A-E (1-5), two new pregnane hexaglycosides, amurensiosides F (6) and I (9), two new 18-norpregnane hexaglycosides, amurensiosides G (7) and H (8), and two new pregnane octaglycosides, amurensiosides J (10) and K (11), were isolated from the MeOH extract of the roots of Adonis amurensis. The structures of the new compounds were determined on the basis of extensive spectroscopic analysis, including two-dimensional (2D) NMR data, and the results of hydrolytic cleavage. The isolated compounds were evaluated for their cytotoxic activity against HSC-2 human oral squamous cell carcinoma cells.

Two new oxypregnane-oligoglycosides named calotroposides A (1) and B (2) have been isolated from the root of Calotropis gigantea (Asclepiadaceae), an Indonesian medicinal plant, and their chemical structures have been elucidated by chemical and spectroscopic methods as 12-O-benzoyllineolon 3-O-β-D-cymaropyranosyl(1→4)-β-D-oleandropyranosyl(1→4)-β-D-olean dropyranosyl(1→4)-β-D-cymaropyranosyl(1→4)-β-D-cymaropyranoside and 12-O-benzoyldeacetylmetaplexigenin 3-O-β-D-cymaropyranosyl(1→4)-β-D-oleandropyranosyl(1→4)-β-D-olean dropyranosyl(1→4)-β-D-cymaropyranosyl(1→4)-β-D-cymaropyranoside, respectively.
