Chemistry, pharmacology and processing method of rhubarb (Rheum species): a review
), Abstract
Rhubarb is a Chinese traditional medicine. Ninety-four compounds belonging to five different classes of compounds (anthraquinone, anthrones, stilbenes, flavonoids and acylglucosides) have so far been identified in rhubarb. These constituents are effective in purgative, clearing heat-fire, removing toxic materials from the body, cooling blood and promoting blood circulation. Recent studies have shown that the appropriate processing methods may directly impact on its remedial activities and chemical compositions. Here, we provide a comprehensive review of the chemical compositions, pharmacological activities and processing methods of rhubarb.
