Tea saponin is a class of structurally complex glycoside compounds. It tastes bitter and pungent, is difficult to dissolve in cold water, has a pH value between 5.6 and 5.7 (slightly acidic), and possesses strong foaming ability that is not affected by water hardness. Therefore, tea with abundant foam generally has a more intense flavor.

Glycoside compounds like tea saponin are widely present in the plant kingdom. For example, ginsenosides in ginseng are antioxidants, and allyl disulfide compounds in garlic and onions also have effects such as enhancing human immunity and fighting cancer.
