Recently, I read some articles saying that saponins accumulation could help in alleviate some abiotic stresses in plant,especially in salinity stress and I am interested to know more about this class of chemical compound.
Saponins are “soapy” triterpenes found in the leaves of some plants. They are typically stored as glycoside conjugates. Pathogenic attack releases glycosidases which cleave the sugar off to release the bioactive saponin. The saponin binds to sterols and its primary mode of action is to bind to fungal membranes and corrupt their integrity. In terms of a potential role in stress tolerance, there is evidence that saponin concentration shows a positive relationship with the magntitude of the stress. One example you could consult is:

Saponins are water soluble bitter substances that foam in aqueous solutions, They lower surface tension.They can lyse red blood cells. Many natural medicinal substances are saponins

Saponin is a poisonous glucoside found in many plants, as in the root of soapwort (Saponaria), in the bark of soap bark (Quillaia), etc. It is extracted as a white amorphous powder, which occasions a soapy lather in solution, and produces a local anæsthesia. Formerly called also struthiin, quillaiin, senegin, polygalic acid, etc. By extension, any one of a group of related bodies of which saponin proper is the type.
