THE EFFECT OF RADIX SALVIAE MILTIORRHIZAE COMPOSITA ON PEROXIDATION OF LOW DENSITY LIPOPROTEIN DUE TO COPPER DICHLORIDE

It is well known that plasma lipoprotein, particularly oxidized LDL, plays an important rolein the pathogenesis of atherosclerosis and atherosclerotic diseases. We used oxidized LDLgenerated by incubating LDL from healthy Persons with copper dichloride as a model to in-vestigate the antioxidate property of Radix Salviae Miltiorrhizae Composita (RSMC). Onphotos, the spot X1 and the spot X2 were clearly found in the control group after the dislysisinto copper dichloride for 24 and 48 hours, but they could not found in the RSMC group.The analysis of the constituents of lipids in LDL (by charring method) showed that afterdislysis the percentages of the spot X1 and the spot X2 in the RSMC group weresignificantly lower tban those in the control group (P< 0.01). The results suggest thatRSMC plays a potential role in antioxidation of lipuls or LDL.
