摘要
本文报道了栀子、金钱草等几种中草药水提取物对鼠肝匀浆脂质过氧化物生成的抑制作用及对超氧阴离子自由基(O_2^-)和羟自由基(·OH)的清除作用。当反应系统中药物浓度(以固体水提取物计)达0.67mg/ml时,金钱草和栀子对小鼠肝匀浆脂质过氧化物生成的抑制率均达100％,对·OH的清除率分别达56.6％和69.1％。当反应系统中药物浓度(以生药计)达8.33mg/ml时,二者对O_2^-的清除率分别达98.5％和100％,效果极为显著。
This paper presents the function of restraining the formation of lipid peroxide in homogenates of mouse liver and the function of eliminating superoxide anion radical O2- and hydroxyl radical· OH of the water extractants of several Chinese herbs such as Glechoma Langituba and Gardenia jasminodes Ellis. When the concentration of extractants of these two herbs in the system of these two herbs reaches 0.67mg/ml (Solid material from water extractants). The ratio of their restraining the formation of lipid superoxide will be 100% and we got 56. 6% and 69. 1 % for the ratio of eliminating hydroxyl radical·OH respectively. When the concentration of both herbs are 8. 33mg/ml (dry herbs), the percentages of elimination of superoxide anion radical O2- are 98. 5% and 100% respectively. The effects are very obvious.
