摘　　要：本实验以乙醇、丙酮和水作为提取剂,对柚皮中的活性物质进行提取,通过正交试验确定出最佳提取条件;在模拟人体胃液环境条件下,采用比色法和紫外光解法分别测定了柚皮提取液对亚硝酸根的清除作用和对亚硝胺合成的阻断作用。结果表明,以乙醇为提取剂的最佳提取条件为:90%乙醇、60℃水浴冷凝回流,提取时间1h;提取液对亚硝胺、亚硝酸钠的最大阻断率和清除率分别为95.5%和91.8%。同时比较了柚皮提取物阻断亚硝胺合成及消除亚硝酸钠的效果。The active substance from Guaixi pomelo peel was extracted through different soluvents such as ethanol, acetone and distilled water. The optimum extraction conditions were obtained by the orthogonal test: 90% ethanol in 60 ℃ water bath condensator extracting 1 hour. The maximum inhibition capability of the extract to nitrosamine elhylamine and scavenging sodium nitrite capability were 95.5% and 91.8%, respectively, and the inhibition capability of the extract to nitrosamine elhylamine and scavenging sodium nitrite capability were compared.
