It has been found that the effects of 1 12 mmol/kg VC-12 on decreasing triglyceride(TG), total cholesterol(TC), low density lipoprotein cholesterol (LDL-c) and lipid peroxide(LPO), and increasing high density lipoprotein cholesterol(HDL-c) and superoxide dismutase(SOD) are similar to those of 2 27 mmol/kg vitamin C. In addition, VC-12(1 12 mmol/kg) can increase the prostacycline(PGI 2) and decrease the thromboxane(TXA 2) even better than vitamin C(2 27 mmol/kg). The above facts demonstrate that the antioxidative activity of VC-12 is higher than twice that of vitamin C. So, ascorbyl-6-laurate may be a novel antioxidant drug against free radical damage.展开更多
