在模拟胃液条件下,采用单因素试验探讨了提取温度、提取时间、料液比、乙醇浓度等因素对橘皮乙醇提取物清除亚硝酸盐能力的影响,在此基础上通过正交试验确定清除亚硝酸盐的最佳工艺条件.结果表明,在65℃下,提取时间为1.5 h,料液比为7:100,乙醇浓度为65％时,清除率最高,达79％以上.4个因素的影响次序为提取温度＞乙醇浓度＞料液比＞提取时间.颜色反应则显示,橘皮乙醇提取物中含有的黄酮类物质主要为黄酮和黄酮醇.

In simulated gastric juice, extraction temperature, ethanol concentration, extraction time and solid-liquid ratio were discussed in order to explore the effects of the extraction condition of orange peel ethanol extracts on nitrite scavenging activity by single factor experiments. And based on these investigation, orthogonal array design was then used to search for the optimum values of the above extraction conditions maximizing its scavenging ratio against nitrite. The results showed that the optimal extraction condition was that extraction te...
