- ... Resolution of soybean saponins on Dowex-1 is influenced by resin particle size, flow rate, temperature and eluting agent. Separations were good when columns of -400 mesh resin were operated at 50° and eluted at slow flow rates either acetic or propionic acid. A linear gradient of 1.5 to 3 N propionic acid separated the saponins into twelve fractions, many of which consisted of two or more componen ...
