Bovine colostrum has lots of active elements,as lactoferrin for example.LF has various bioactive functions such as broad-spectrum antimicrobial activity, promotion of iron transfer and absorption, immunomodulatory effects, regulation of inflammatory reactions, antibviral activity, and inhibition lf lipid peroxidation. but most of the active elements have not been fully used and wasted much in our country.As a rustle ,if we can make full use of Bovine colostrums, it will promote food production , has obvious social and economic benefits.LF was purified by ion exchange chromatography from bovine colostrums. At last it was measured by SDS-PAGE, Enzyme-linked immunosorbent assay and HPLC. Keywords：Bovine colostrums；Lactoferrin；Electrophoresis；ELISA；Extraction 目 录
