Objectives: Hyangsapyungwisan (HPS) has been used for treatment of cardiovascular diseases including of arthralgia, myalgia in traditional Korean medicine. However, the medical actions of HPS have not been clearly investigated. The aim of this study was to elucidate the antiradical and antioxidant activity of the extract for herb-acupuncture (HPS-HA) obtained from HPS.
Methods & Results: HPS-HA exhibited a stronger inhibition rate (55.5%) on lipid peroxidation of rat liver homogenate induced by -ascorbic acid. In addition, HPS-HA markedly interfered with hydroxylradical generation through iron ions chelating action. While pro-oxidant effect of HPS-HA was nearly undetectable at concentrations of 0.5-10㎎/mL. Moerover, HPS-HA revealed a potent antiradical activities on 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radicals, superoxide anions, nitric oxide and peroxynitrite. Furthermore, HPS-HA inhibited copper- and AAPH-mediated oxidation of human low-density lipoprotein (LDL), and also suppressed the relative electrophoretic mobility of LDL. HPS-HA showed strong protective activity against oxidative damage of HUVECs induced by SIN-1.
Conclusions: These results suggest that HPS-HA may be effective in protecting against oxidative diseases.
