The in vitro antioxidation effect of XMSol on LDL / 第三军医大学学报

ABSTRACT

Objective To explore the in vitro antioxidation effect of Xinmaishen oral liquid(XMSol, a Chinese patent medicine) on low density lipoprotein(LDL). Methods Serum containing XMSol was prepared by serum pharmacological method. The oxidized LDL was obtained by 0.5 mg/ml of LDL in the presence of 10 ?mol/L CuSO 4. XMSol, CuSO 4 and serum containing XMSol and CuSO 4 were added to LDL for incubation. Content of MDA was determined and the antioxidation effect of XMSol was evaluated. Results XMSol could reduce MDA production due to oxidation of LDL in a dose dependent manner. Conclusion XMSol can inhibit the in vitro oxidation of LDL dose dependently.
