Abstract

From Oxytropis ochrocephala Bunge, four saponins 1, 2, 3, and 4 were isolated. Saponins 1 and 2 are new compounds. The common genuine aglycone of the saponins is soyasapogenol B. The structures of those saponins were established by means of 13C-NMR, MS analyses, and chemical methods. In addition, a new interesting artifact aglycone 6 was obtained from the hydrolysate of these saponins and its structure was elucidated by spectral analyses and chemical transformations.

Key words
