【摘要】:在体外模拟人体胃液条件下,采用分光光度法测定了夏枯草水提取物、醇提取物对亚硝酸盐的清除率以及对亚硝胺合成的阻断率,并与常用抗氧化剂维生素C进行比较。结果表明:随反应质量浓度的提高、作用时间的延长,夏枯草提取物对亚硝酸钠的清除能力和阻断亚硝胺合成能力有明显提高。根据不同作用时间的清除效果及阻断亚硝胺合成效果的对比,可以得知,120 min为较佳的作用时间。通过与维生素C比较分析得出,夏枯草提取物具有较强的亚硝酸钠清除能力和阻断亚硝胺合成的能力。
[Abstract]:Under the condition of simulated human gastric juice in vitro, the water extract and alcohol extract of Prunella vulgaris were determined by spectrophotometry. The removal rate of nitrite and the blocking rate of nitrosamine synthesis were determined by spectrophotometry. The results were compared with those of vitamin C, a common antioxidant. The results showed that with the increase of the reaction concentration and the prolongation of the action time, the scavenging ability of the extract of Prunella vulgaris to sodium nitrite and the ability to block the synthesis of nitrosamines were obviously improved. According to the scavenging effect of different action time and the comparison of blocking the synthesis of nitrosamine, we can know that the best action time is 120 min. Compared with vitamin C, the extract of Prunella vulgaris has strong ability of removing sodium nitrite and blocking the synthesis of nitrosamines.
