Abstract

The saponin mixt. isolated from M. glacialis was resolved chromatog. into 4 main individual components, marthasterosides A1, A2, B, and C. The isolated sulfated steroidal glycosides were characterized by 1H-NMR, 13C-NMR, fast atom bombardment mass spectrometry, and gas-liq. chromatog. anal. of the sugars after acid hydrolysis. Marthasterosides A1 and A2 contained the aglycon thornasterol A and 6 sugar units. Marthasterosides B and C contained 5 sugar units; their aglycons were marthasterone and dihydromarthasterone, resp. In all compds. the sulfate group is attached at C-3 of the steroid.
