| | SMILAGENIN Usage And Synthesis |
| Definition | ChEBI: An oxaspiro compound that is(5beta,25R)-spirostan substituted by a beta-hydroxy group at position 3. | | Purification Methods | Chromatograph smilagenin on active Al2O3 and elute with *C6H6, then recrystallise it from Me2CO, aqueous EtOH (m 187-188o) or MeOH. The acetate crystallises from MeOH with m 152o and [] D 25 -59.6o, [] 546 25 –68.9o (c 0.25, CHCl3). [Askew J Chem Soc 1399 1936 and 1402 1936, Scheer et al.
