[Abstract]
Rehmannia glutinosa, belonging to Scrophulariaceae family, is widely distributed in China, and its root tubers are commonly called "Dihuang" in Chinese. So far large quantity of unique iridoids have been isolated from the plant, together with other types of active principles, such as megastigmas, phenethyl alcohols, triterpenes, flavonoids, lignans, alkaloids, phenolic acids, and sugars. The plant has the significant effects on cardiovascular diseases, neuroprotection, diabetes and its complications, osteoporosis, and hyperlipemia, and the active principles have entitled the plant to serve several different bioactivities including neuroprotective, hypoglycemic, lipid-lowering, anti-oxidant, antifatigue, and immuno-regulation effects. This paper reviews in detail the categorization of chemical constituents from R. glutinosa and their pharmacological activities.
