英文摘要：

Objective：To investigate effects of dichloromethane extraction sites from raw and processed Fructus Corni on ageing human embryonic lung cells induced by D-galactose.Methods：Taking human embryonic lung cells as materials and MTT、SOD、NO as indicators,the impairment of human embryonic lung cells induced by D-galactose and protective function of dichloromethane extraction sites from raw and processed Fructus Corni were observed by making the cellular ageing model of D-galactose,and effects of dichloromethane extraction sites from raw and processed Fructus Corni on ageing pathways were further discussed by Rt-PCR test.Results：Dichloromethane extraction sites from raw and processed Fructus Corni exerted certain effect on proliferation of ageing human embryonic lung cells induced by D-galactose,showing protective effect on their antioxidant systems and having regulated effect on their pathways related to ageing.Conclusion：Dichloromethane extraction sites from raw and processed Fructus Corni have protective effects on ageing human embryonic lung cells induced by D-galactose.
