摘要: 本文于不同体系中体外检测了市售五种保健品对自由基的清除作用。它们对1,1-二苯基-2-苦肼基自由基(DPPH·)的清除作用呈量效关系,浓度越高,清除作用越强;对羟自由基(·OH)的清除作用有一个最佳浓度值,高于或低于此值时清除作用均减弱;对超氧阴离子自由基()的清除作用各不相同。它们对自由基的清除作用可能是其分子药理学的基础之一。

Abstract: The free radical in vitro scavenging effects of 5 kinds healthcare medicines were studied.Their scavenging effects to 1,1-Diphenyl-2-picryl -h ydrazyl (DPPH·) had a quantitative relationship ,the larger the concentration,the stronger the scavenging effects.Scavenging effects to hydroxyl radical (·OH) had the best concentration.The scavenging effects would be weakened without it.Scavenging effects to superoxide radical ()were defferent with each other.The free radical scavenging effects might be of the basis of molecular pharmacology.
