Three kinds of saponin, named senegin-II, -III, and -IV, were isolated from Senegae radix (root of Polygala senega LINNE var. latifolia TORRY et GRAY, Polygalaceae). Senegin-II, C_<70>H_<104>O_<32>・4H_2O, colorless needles, mp 247-248°, is a glucoside of presenegenin bonded with rhamnose, fucose, xylose, galactose, glucose, and 3,4-dimethoxycinnamic acid. Senegin-III, C_<69>H_<102>O_<31>・4H_2O, crystalline powder, mp 247-248°(decomp.), is a glucoside of presenegenin bonded with rhamnose, fucose, galactose, glucose and 4-methoxycinnamic acid. Senegin-IV, C_<75>H_<112>O_<35>・4H_2O, crystalline powder, mp 250°(decomp.), is a glucoside of presenegenin bonded with 2 moles of rhamnose, fucose, xylose, galactose, glucose, and 4-methoxycinnamic acid. In addition to these substances, the presence of 1,5-anhydro-D-sorbitol and phenolic glycosides was detected.
