Comparative Study on Antioxidative Effects of Mori Ramulus and Mori Cortex

In recent year, We are concerned about anti-aging, disease-prevention, longevity, so many methods are used in solving this problem. And Those are related with antioxidative ability. Recently, We heard that Mori Cortex was known to reduce the hypertension and was helpful in promoting health, and Mori Ramulus was effective against obesity, etc. So, This study was performed to investigate the antioxidative effect of hot-water extracts of Mori Cortex and Mori Ramulus used for 3 methods, those are DPPH radical scavenging activity, Nitric oxide(NO) radical scavenging activity and Bovine serum albumin(BSA). And we compared Mori Cortex and Mori Ramulus on Antioxidative Effects. The results of this study were as follows: We measured levels of DPPH radical scavenging activity and Nitric oxide(NO) radical scavenging activity. And we obtained results that Mori Ramulus was most effective with the concentration of 5 $mg/m{\ell}$, and Mori Cortex was most effective with the concentration of 2.5 $mg/m{\ell}$, And we examined the antioxidative effects of Mori Ramulus and Mori Cortex with $CU^{2+}/H_20_2$-induced Bovine serum albumin(BSA). And we obtained that antioxidative ability was increased after 1.25 $mg/m{\ell}$ and that was most effective with the concentration of 5 $mg/m{\ell}$ on both of them. And antioxidative ability of Mori Cortex was better than Mori Ramulus(p<0.05). So I guess that hot-water extracts of Mori Ramulus and Mori Cortex have effects on antioxidative ability, but Mori Cortex is better than Mori Ramulus on antioxidation. Hereafter we need differential experimental methods of antioxidative effect on both of them.
