Chlorogenic acid, a phenolic compound found ubiquitously in plants, is an in vitro antioxidant and metal chelator, some derivatives of chlorogenic acid are hypoglycemic agents and may affect lipid metabolism;in vivo, chlorogenic acid can improve glucose tolerance, decrease some plasma and liver lipids, and improve mineral pool distribution.

Emodin-8-O-beta-D-glucoside extracted from the traditional Chinese medicinal herb Polygonum cuspidatum Sieb. et Zucc is widely used to treat acute hepatitis possibly by antioxidative mechanisms; it is able to provide neuroprotection against cerebral ischemia-reperfused injury and glutamate induced neuronal damage through exerting antioxidative effects and inhibiting glutamate neurotoxicity.

Geniposide, a major iridoid found in fruit, is widely used in Asian countries for its anti-inflammatory, and anti-apoptotic activities, the anti-apoptotic activities is due to its modulation of and -related factors (p53, Bax, Bcl-2 and Caspase-3) in LPS-induced mouse mastitis.

Astilbin has insecticidal, antioxidant, antibacterial, and anti-inflammatory activities, it may act as an efficient therapeutic agent for arthritis like cyclosporine A but with less toxicity, its mechanism includes a selective suppression on lymphocyte functions via reducing MMP and NO production. Astilbin can exert an early renal protective role to diabetic nephropathy (DN), inhibit production of transforming growth factor-beta1 (TGF-beta1) and connective tissue growth factor (CTGF).Astilbin also alleviates contact hypersensitivity through a unique mechanism involving a negative cytokine regulation through stimulating IL-10, which is distinct from the immunosuppressant cyclosporin A.

Aconitine, one of the major Aconitum alkaloids, is a highly toxic compound from the Aconitum species, it appears to exert a long-lasting cholinergic action in the causation of severe arrhythmias leading to death.

Digoxin is a classical Na,K-ATPase inhibitor, with selectivity for the α2β3 isoform over the common α1β1 isoform, used in the treatment of atrial fibrillation and heart failure. Digoxin and other cardiac glycosides can inhibit hypoxia-inducible factor 1 (HIF-1)α synthesis and block tumor growth.

Emodin, a natural anthraquinone derivative isolated from Rheum palmatum L., exhibits anti-cancer effect on several human cancers such as liver cancers and lung cancers, treatment with 50 microM emodin resulted in a pronounced release of cytochrome c, activation of caspase-2, -3, and -9, and apoptosis in human lung adenocarcinoma A549 cells.
