Barfoed b. Test tube having foam of 1 cm height is noted and concentration of these is taken into consideration.
Saponins possess surface-active or detergent properties because the carbohydrate portion of the molecule is water-soluble, whereas the sapogenin is fat-soluble. They are sparingly soluble in chloroform, ethyl acetate and other organic solvents. The reaction occurs in two sequential steps: in first reaction gelatinases hydrolyze gelatin into polypeptides and then polypeptides are further . Flavonoid glycosides . 184.108.40.206.

9. Saponins are a class of substances with a rigid skeleton of at least four hydrocarbon rings to which sugars in groups of one or two are attached (usually not more than 10 units).
Certain other substances, although possessing the property of froth formation in these processes, exclude practically all solid matter from the froth. This test is used to determine the ability of an organism to produce extracellular proteolytic enzymes (gelatinases) that liquefy gelatin, a component of vertebrate connective tissue. Saponins were identified by diluting the plant extract (1 ml) with distilled water (20 ml) and shaking in a graduated cylinder for 15 min. 11.
