摘要
采用对氨基苯磺酸-盐酸萘乙二胺法测定了槲皮素、槲皮素-Al及槲皮素-B三种物质对亚硝酸钠的清除率.结果表明,槲皮素及其配合物对亚硝酸钠具有一定的清除作用,且槲皮素-Al及槲皮素-B配合物对亚硝酸钠的清除率明显高于槲皮素.在最佳反应条件下,即质量浓度为0.4 mg/mL的清除剂用量1.2 mL,反应温度50℃,反应时间30 min,槲皮素对亚硝酸钠的清除率为25.8%,而槲皮素-Al和槲皮素-B对亚硝酸钠的清除率分别达到了80.2%和84.1%,且槲皮素-B的清除率稍高于槲皮素-Al.
Abstract
The scavenging rate of quercetin,quercetin-Al and quercetin-B on sodium nitrite was determined by aminobenzene sulfonic acid-hydrochloric acid naphthalene ethylenediamine method.The results showed that quercetin and its quercetin complexes had a certain scavenging activity on sodium nitrite.The scavenging rate of quercetin-Al and quercetin-B on sodium nitrite was significantly higher than that of quercetin.Under the optimal reaction conditions of 0.4 mg/ml scavenging agent addition 1.2 mL,reaction temperature 50 ℃ and temperature 30 min,the scavenging rate of quercetin on sodium nitrite was 25.8%,while the scavenging rate of quercetin-Al and quercetin-B on sodium nitrite were 80.2% and 84.1%,respectively.The scavenging rate of quercetin-B was slightly higher than that of quercetin-Al.
