Yucca tree roots have saponin glycosides. They are anthraquinone derivatives and dimeric glycosides. "Tinospora" contains diverse phytochemicals, including alkaloids, phytosterols, glycosides, and mixed other chemical compounds. Ginsenosides or panaxosides are a class of natural product steroid glycosides and triterpene saponins. Common defenses include&colon; cardiac glycosides (or cardenolides), pyrrolizidine alkaloids, pyrazines and histamines. The chemical structure of ginseng consists of ginsenosides and saponin glycosides. Bilberries and blueberries contain diverse anthocyanins, including delphinidin and cyanidin glycosides. Chemically, these are polypropionate lactone glycosides. The anthocyanins are subdivided into the sugar-free anthocyanidin aglycones and the anthocyanin glycosides. Chemical constituents include salicylic acid, flavone glycosides, essential oils, and tannins. Na/K-ATPase by binding to the same receptor sites as the digitalis glycosides such as ouabain. These were the cardiac glycosides, quinidine, propranolol, lidocaine and diphenylhydantoin. Larvae feed exclusively on milkweed and consume protective cardiac glycosides. Toxic cardiac glycosides occur in the roots. TRPM5 is activated by the sweet glycosides found in the stevia plant.
