Neuroprotective Effects of Anthraquinones from Rhubarb in Central Nervous System Diseases

Abstract EN

Rhubarb is a well-known traditional Chinese medicine; it has been used in China for thousands of years.

Rhubarb anthraquinones are the major medicinal ingredients derived from rhubarb including emodin, aloe-emodin, chrysophanol, rhein, physcion, and danthron.

These different anthraquinone derivatives alone or in combination play a therapeutic role in central nervous system diseases (CNSD), such as cerebral ischemic stroke, intracerebral hemorrhage, traumatic brain injury, brain tumor, Alzheimer’s disease, depression, and others.

We review the experimental studies on these six anthraquinones in the treatment of CNSD by consulting literature published in the last 20 years in PubMed and then give a future perspective on it.

In the end of this paper some deficiencies related to these studies also have been pointed out.
