“…T. chinensis, T. wattii, and T. yunnanensis are main sources of spirostanol and furostanol saponins. Sixty-five compounds were assigned as spirostanol saponins (Table 1 and Figure 2), 2,[7][8][9][10]21,22,24,28,[31][32][33]35,36,39 while compounds 85 to 150 are furostanol saponins (Table 1 and Figure 3). 5,8,10,18,22,24,31,35,37,[39][40][41][42][43][44][45][46][47] Taking spirostanol saponins into consideration, glycosylation generally happens at C-1, C-3, C-5, and C-24.…”
