By network search,classification and collection,this paper summarizes the chemical constituents of cornel iridoid glycosides which have reported in domestic and foreign literatures. And the pharmacological effects and pharmacokinetics characteristics of loganin and morroniside with the highest contents are sorted out. The pharmacological effects include inhibition on neurodegenerative diseases(inhibition on Ca,2+, imbalance,suppression on oxidative stress damage,protection on nerve,inhibition on cell apoptosis and anti-inflammation),anti-thrombosis,anti-melanin and anti-diabetes.
