| 摘 要： | 以清除亚硝酸盐及阻断亚硝胺合成的百分率为综合评价指标，研究了半仿生法下龙胆草提取液体外清除亚硝酸盐和阻断亚硝胺合成的能力．研究结果表明，半仿生法下在70℃，用1：15的料液比提取3次，每次1．5h，所得结果最佳，对亚硝酸盐最大清除率可达90．79％，亚硝胺合成的阻断率最大达65．23％，分别是常规提取方法的4倍、1．5倍．

| Abstract: | This paper studied the ability of eliminating nitrite and breaking nitrosamine synthesis by Gen tiana scabra Bunge in vitro with semi-bionic extraction methodology,according to the percentages of eliminating nitrite and breaking nitrosamine synthesis.The results showed that:the best effects reached when extracting 3 times with the ratio to extraction liquid 1:15,70 ℃,and 1.5 h for each time with semi-bionic extraction methodology.The max capability of eliminating nitrite was 87.14%.The max capability of breaking nitrosamine synthesis was 65.23%.These percentages are 4 times and 1.5 times higher than using the usual methods. |
