摘要

用动态吸附的方法对γ辐照芦丁和黄芩甙的空气饱和乙醇体系中产生的过氧化氢进行分离，测定了辐照生成的过氧化氢的,G,值，得到了与前人不同的结果，并分析了产生分歧的原因。提出并确立了正确的方法：准确测定黄酮类化合物辐照体系中的过氧化氢值，必须先用柱色谱法将过氧化氢从辐照体系中分离出来再进行测定，再扣除黄酮类化合物因自氧化而产生的过氧化氢的量。采用6.93Gy min,-1,的剂量率，测得1×10,-3,mol • dm,-3,的芦丁和黄芩甙乙醇溶液中，经,γ,辐照后产生的过氧化氢,G,值分别为5.5±0.2和7.3±0.2。与纯乙醇相比，辐照后过氧化氢的,G,值增加。

Abstract

γ, Irradiated rutin and baicalin ethanol solutions saturated with air were eluted through alumina columns and the ,G, values of hydrogen peroxide generated in the solutions were measured. Different results from former works were obtained and the reasons of the difference were discussed. A precise method was established as follows : hydrogen peroxide should be separated from flavonoids by passing the flavonoids ethanol solutions through alumina columns before the measurement and the amount of hydrogen peroxide generated from self—oxidation of the flavonoids should be deducted. Under a dose rate of 6.93Gy min,-1, the ,G, values of hydrogen peroxide in ,γ, irradiated rutin and baicalin ethanol solutions saturated with air were determined to be 5.5±0.2 and 7.3±0.2, separately. After irradiation of rutin— and baicalin—O,2,—ethanol solutions, the ,G, values of hydrogen peroxide were increased comparing with that of pure ethanol—O,2, solution.
