[Proteins and saponins in the lipid preparation obtained by extraction of soybean flour]. / Belki i saponiny v lipidnom preparate, poluchennom pri ékstraktsii soevoi muki.

A complex lipid preparation was obtained by extraction of soybean flour with organic solvents. This preparation was shown to include not only phospholipids (major components), but also up to 30% saponins. These compounds were identified by TLC, HPLC, and 1H-NMR spectroscopy. Minor components of the lipid extract were represented by polypeptides associated with phospholipids via electrostatic or hydrophobic forces.
