Emodin (from Rheum emodi, a Himalayan rhubarb) is a purgative resin, 6-methyl-1,3,8-trihydroxyanthraquinone, from rhubarb, buckthorn and Japanese knotweed (Fallopia japonica syn. Polygonum cuspidatum).^[3] It is also produced by many species of fungi, including members of the genera Aspergillus, Pyrenochaeta, and Pestalotiopsis, inter alia. Synonyms for emodin include emodol, frangula emodin, rheum emodin, 3-methyl-1,6,8-trihydroxyanthraquinone, Schuttgelb, and Persian Berry Lake.^[4]

Pharmacology

Emodin is being studied as a potential agent that could reduce the impact of type 2 diabetes. It is a potent selective inhibitor of the enzyme 11β-HSD1.^[5] In studies in obese mice, emodin limits the effect of glucocorticoids and may therefore ameliorate diabetes and insulin resistance.^[6]

Pharmacological studies have demonstrated that emodin when isolated from rhubarb exhibits anti-cancer effects on several human cancers, including human pancreatic cancer.^[7]^[8]^[9] Emodin in rhubarb extracts may also have neuroprotective properties against glutamate toxicity.^[10]

Aloe-emodin (1,3,8-trihydroxyanthraquinone) is a variety of emodin found in Socotrine, Barbados, and Zanzibar aloes, but not in Natal aloes.^{[citation needed]}

Emodin is also shown to block cytomegalovirus infections as well as herpes simplex. Research is currently being performed in this area.

List of species that produce emodin
