Tomatine

Some of these, such as α-chaconines and α-tomatines, are generally antiparasitic (general prohibitions; see also sections 3.231, 3.2333, 8.4213).

However, because of the marked antifungal activity of tomatine and other saponins, these preformed compounds are believed to be involved in host resistance towards saponin-sensitive fungi.
