    • The furostanol saponins (1 and 2) were obtained as a mixture of C-22 hydroxy and C-22 methoxyforms. The C-22 hydroxy form present in the mixture was completely converted to the C-22 methoxy form by treatment with hot McOH, and the structural elucidation of 1 and 2 was carried out with the C-22 methoxy form. The C-22 configuration was shown to be α by an NOE correlation between the C-22 methoxy protons and H-16 proton.
