Chaenomeles sinensis with a wide range of medical values was widely planted in our country

and a series of studies were carried out by domestic and foreign scholars. Studies showed that C. sinensis had organic acids

flavonoids

triterpenoids

steroids

lignans and other compounds

and exhibited antitumor

hepatoprotective

immunosuppressive and antibacterial activities. It was commonly used in combination with other Chinese herbal medicines to treat rheumatoid joint pain

lumbocrural pain and limbs anesthesia in clinic application. The studies on the chemical constituents and pharmacological activities of C. sinensis were more and more deep recently

and the results showed that C. sinensis also had polysaccharides

lignin glycosides

oxylipins

biphenyls and some other new compounds

and exhibited the effects of antioxidant

analgesic

anti-inflammatory

antibacterial

hpyerglycemic

anti-cancer

antidementia

anti-influenza virus

antianaphylaxis and choline acetyl transferase activator. Although the correlations between its material basis and pharmacological activity were further studied

the studies were not comprehensive

and still needed further research and exploration. By reviewing the domestic and abroad literature in recent years

the chemical constituents and pharmacological activities of C. sinensis were summarized in order to provide certain scientific basis for further research and development on C. sinensis.
