Procedure
When it is subjected to methanolysis, it gives 1 mol each of methylglucoside, methylgalactoside, methylarabinoside and methylglucuronide. A completely methylated compound (C68H116O24) obtained by methylation of soyasaponin A2 with methyl iodide, dimethyl sulfoxide and sodium hydride gives 1 mol each of methyl 3,4-di-O-methylglucopyranoside, methyl 2,4-di-O-methylarabinopyranoside, methyl 2,3,4,6-tetra-O-methylgalactopyranoside and methyl 2,3,4,6-tetra-O-methylglucopyranoside as methylated sugar, and 1 mol of 3,22,24-tri-O-methyl soyasapogenol A as methylated sapogenol, when subjected to methanolysis after reduction.
